     MODE FOR CARRYING OUT THE INVENTION 
     Definition 
     In the present specification, a hydrogen atom means an atom including isotopes different in the number of neutrons, namely, a protium, a deuterium and a tritium. 
     In the present specification, to a bondable position in which a symbol such as “R”, or “D” representing a deuterium atom is not specified in a chemical formula, a hydrogen atom, that is, a light hydrogen atom, a deuterium atom, or a tritium atom is bonded thereto. 
     In the present specification, a term “ring carbon atoms” represents the number of carbon atoms among atoms forming a subject ring itself of a compound having a structure in which atoms are bonded in a ring form (for example, a monocyclic compound, a fused ring compound, a cross-linked compound, a carbocyclic compound or a heterocyclic compound). When the subject ring is substituted by a substituent, the carbon contained in the substituent is not included in the number of ring carbon atoms. The same shall apply to the “ring carbon atoms” described below, unless otherwise noted. For example, a benzene ring has 6 ring carbon atoms, a naphthalene ring has 10 ring carbon atoms, a pyridine ring has 5 ring carbon atoms, and a furan ring has 4 ring carbon atoms. Further, for example, a 9,9-diphenylfluorenyl group has 13 ring carbon atoms, and a 9,9′-spirobifluorenyl group has 25 ring carbon atoms. 
     Further, when the benzene ring or the naphthalene ring is substituted by an alkyl group as a substituent, for example, the number of carbon atoms of the alkyl group is not included in the ring carbon atoms. 
     In the present specification, a term “ring atoms” represents the number of atoms forming a subject ring itself of a compound having a structure in which atoms are bonded in a ring form (for example, a monocycle, a fused ring and a ring assembly) (for example, a monocyclic compound, a fused ring compound, a cross-linked compound, a carbocyclic compound or a heterocyclic compound). The term “ring atoms” does not include atoms which do not form the ring (for example, a hydrogen atom which terminates a bond of the atoms forming the ring) or atoms contained in a substituent when the ring is substituted by the substituent. The same shall apply to the “ring atoms” described below, unless otherwise noted. For example, a pyridine ring has 6 ring atoms, a quinazoline ring has 10 ring atoms, and a furan ring has 5 ring atoms. A hydrogen atom bonded with a carbon atom of the pyridine ring or the quinazoline ring or an atom forming the substituent is not included in the number of the ring atoms. 
     In the present specification, a term “XX to YY carbon atoms” in an expression of “substituted or unsubstituted ZZ group having XX to YY carbon atoms” represents the number of carbon atoms when the ZZ group is unsubstituted. The number of carbon atoms of a substituent when the ZZ group is substituted is not included. Here, “YY” is larger than “XX”, and “XX” and “YY” each mean an integer of 1 or more. 
     In the present specification, a term “XX to YY atoms” in an expression of “substituted or unsubstituted ZZ group having XX to YY atoms” represents the number of atoms when the ZZ group is unsubstituted. The number of atoms of a substituent when the group is substituted is not included. Here, “YY” is larger than “XX”, and “XX” and “YY” each mean an integer of 1 or more. 
     A term “unsubstituted” in the case of “substituted or unsubstituted ZZ group” means that the ZZ group is not substituted by a substituent, and a hydrogen atom is bonded therewith. Alternatively, a term “substituted” in the case of “substituted or unsubstituted ZZ group” means that one or more hydrogen atoms in the ZZ group are substituted by a substituent. Similarly, a term “substituted” in the case of “BB group substituted by an AA group” means that one or more hydrogen atoms in the BB group are substituted by the AA group. 
     Hereinafter, the substituent described herein will be described.

     In the formulas (XY-65) to (XY-75), X B  is an oxygen atom or a sulfur atom. 
     Herein, a case where “one or more sets of two or more groups adjacent to each other are bonded with each other to form a substituted or unsubstituted and saturated or unsaturated ring” will be described by taking, as an example, a case of an anthracene compound represented by the following formula (XY-80) in which a mother skeleton is an anthracene ring. 
     
       
         
         
             
             
         
       
       
         
         
             
             
         
       
     
     For example, two adjacent to each other into one set when “one or more sets of two or more groups adjacent to each other are bonded with each other to form the ring” among R 921  to R 930  include R 921  and R 922 , R 922  and R 923 , R 923  and R 924 , R 924  and R 930 , R 930  and R 925 , R 925  and R 926 , R 926  and R 927 , R 927  and R 928 , R 928  and R 929 , and R 929  and R 921 . 
     The above-described “one or more sets” means that two or more sets of two groups adjacent to each other may simultaneously form the ring. For example, a case where R 921  and R 922  are bonded with each other to form a ring A, and simultaneously R 925  and R 926  are bonded with each other to form a ring B is represented by the following formula (XY-81). 
     
       
         
         
             
             
         
       
     
     A case where “two or more groups adjacent to each other” form a ring means that, for example, R 921  and R 922  are bonded with each other to form a ring A, and R 922  and R 923  are bonded with each other to form a ring C. A case where the ring A and ring C sharing R 922  are formed, in which the ring A and the ring C are fused to the anthracene mother skeleton by three of R 921  to R 923  adjacent to each other, is represented by the following (XY-82). 
     
       
         
         
             
             
         
       
     
     The rings A to C formed in the formulas (XY-81) and (XY-82) are a saturated or unsaturated ring. 
     A term “unsaturated ring” means an aromatic hydrocarbon ring or an aromatic heterocyclic ring. A term “saturated ring” means an aliphatic hydrocarbon ring or an aliphatic heterocyclic ring. 
     For example, the ring A formed by R 921  and R 92  being bonded with each other, represented by the formula (XY-81), means a ring formed by a carbon atom of the anthracene skeleton bonded with R 921 , a carbon atom of the anthracene skeleton bonded with R 922 , and one or more arbitrary elements. Specific examples include, when the ring A is formed by R 921  and R 922 , a case where an unsaturated ring is formed of a carbon atom of an anthracene skeleton bonded with R 921 , a carbon atom of the anthracene skeleton bonded with R 922 , and four carbon atoms, in which a ring formed by R 921  and R 922  is formed into a benzene ring. Further, when a saturated ring is formed, the ring is formed into a cyclohexane ring. 
     Here, “arbitrary elements” are preferably a C element, a N element, an O element and a S element. In the arbitrary elements (for example, a case of the C element or the N element), the bond(s) that is(are) not involved in the formation of the ring may be terminated by a hydrogen atom, or may be substituted by an arbitrary substituent. When the ring contains the arbitrary elements other than the C element, the ring to be formed is a heterocyclic ring. 
     The number of “one or more arbitrary elements” forming the saturated or unsaturated ring is preferably 2 or more and 15 or less, more preferably 3 or more and 12 or less, and further preferably 3 or more and 5 or less. 
     As specific examples of the aromatic hydrocarbon ring, a structure in which the aryl group described in specific example group G1 is terminated with a hydrogen atom may be mentioned. 
     As specific examples of the aromatic heterocyclic ring, a structure in which the aromatic heterocyclic group described in specific example group G2 is terminated with a hydrogen atom may be mentioned. 
     As specific examples of the aliphatic hydrocarbon ring, a structure in which the cycloalkyl group described in specific example group G6 is terminated with a hydrogen atom may be mentioned. 
     When the above-described “saturated or unsaturated ring” has a substituent, the substituent is an “arbitrary substituent” as described below, for example. When the above-mentioned “saturated or unsaturated ring” has a substituent, specific examples of the substituent refer to the substituents described in above-mentioned “the substituent described herein”. 
     In one embodiment of the present specification, the substituent (hereinafter, referred to as an “arbitrary substituent” in several cases) in the case of the “substituted or unsubstituted” is a group selected from the group consisting of 
     an unsubstituted alkyl group having 1 to 50 carbon atoms, 
     an unsubstituted alkenyl group having 2 to 50 carbon atoms,

     —O—(R 904 ), 
     —S—(R 905 ) 
     —N(R 906 )(R 907 ) 
     wherein, 
     R 901  to R 907  are independently 
     a hydrogen atom, 
     a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, 
     a substituted or unsubstituted cycloalkyl group having 3 to 50 ring carbon atoms, 
     a substituted or unsubstituted aryl group having 6 to 50 ring carbon atoms, or 
     a substituted or unsubstituted monovalent heterocyclic group having 5 to 50 ring atoms; and 
     when two or more of R 901  to R 907  exist, two or more of R 901  to R 907  may be the same with or different from each other, 
     a halogen atom, a cyano group, a nitro group, 
     an unsubstituted aryl group having 6 to 50 ring carbon atoms, and 
     an unsubstituted monovalent heterocyclic group having 5 to 50 ring atoms. 
     In one embodiment, the substituent in the case of “substituted or unsubstituted” is a group selected from the group consisting of 
     an alkyl group having 1 to 50 carbon atoms, 
     an aryl group having 6 to 50 ring carbon atoms, and 
     a monovalent heterocyclic group having 5 to 50 ring atoms. 
     In one embodiment, the substituent in the case of “substituted or unsubstituted” is a group selected from the group consisting of 
     an alkyl group having 1 to 18 carbon atoms, 
     an aryl group having 6 to 18 ring carbon atoms, and 
     a monovalent heterocyclic group having 5 to 18 ring atoms. 
     Specific examples of each group of the arbitrary substituent described above are as described above. 
     Herein, unless otherwise specified, the saturated or unsaturated ring (preferably substituted or unsubstituted and saturated or unsaturated five-membered or six-membered ring, more preferably a benzene ring) may be formed by the arbitrary substituents adjacent to each other. 
     Herein, unless otherwise specified, the arbitrary substituent may further have the substituent. Specific examples of the substituent that the arbitrary substituent further has include to the ones same as the arbitrary substituent described above.

     Example 1 
     (Fabrication of Organic EL Device) 
     A glass substrate of 25 mm by 75 mm by 1.1 mm thick with an ITO transparent electrode (anode) (manufactured by GEOMATEC Co., Ltd.) was subjected to ultrasonic cleaning with isopropyl alcohol for 5 minutes, and then subjected to UV-ozone cleaning for 30 minutes. The thickness of the ITO was 130 nm. 
     The cleaned glass substrate with a transparent electrode was mounted in a substrate holder of a vacuum vapor deposition apparatus. First, the compound HI was deposited on the surface where the transparent electrode was formed so as to cover the transparent electrode, thereby to form a 5 nm-thick HI film was formed. This HI film serves as a hole-injecting layer. 
     Subsequent to the formation of the HI film, the compound HT-1 was deposited, whereby a 80 nm-thick HT-1 film was formed on the HI film. This HT-1 film serves as a hole-transporting layer (first hole-transporting layer). 
     Subsequent to the formation of the HT-1 film, the compound HT-2 was deposited, whereby a 10 nm-thick HT-2 film was formed on the HT-1 film. This HT-2 film serves as an electron blocking layer (second hole-transporting layer). 
     On the HT-2 film, compound BH-1 (host material) and compound BD-1 (dopant material) were co-deposited such that the amount ratio of BD-1 (mass ratio) became 4 mass %, whereby a 25 nm-thick BH-1:BD-1 film was formed. The BH-1:BD-1 film serves as an emitting layer. 
     On the emitting layer, compound ET-1 was deposited, whereby a 10 nm-thick ET-1 film was formed. This ET-1 film serves as a hole barrier layer. 
     On the ET-1 film, compound ET-2 was deposited, whereby a 15 nm-thick ET-2 film was formed. This ET-2 film serves as an electron transporting layer. On this ET-2 film, LiF was deposited, whereby a 1 nm-thick LiF film. On this LiF film, metal Al was deposited, whereby a 80 nm-thick metal cathode was formed. By the above-mentioned procedures, an organic EL device was fabricated. 
     The resultant organic EL device has the following layer structure: ITO(130)/HI(5)/HT-1(80)/HT-2(10)/BH-1:BD-1 (25:4 mass %)/ET-1 (10)/ET-2(15)/LiF(1)/Al(80). 
     The numerical value in the parenthesis indicates the film thickness (unit: nm). 
     Materials used in Example 1 and the below-mentioned Examples and Comparative Examples are shown below. 
                                                                                                                                                                                                             
(Evaluation of Organic EL Device)
 
     A voltage was applied to the resulting organic EL device such that the current density became 50 mA/cm 2 , and the time taken until the luminance became 95% of the initial luminance (lifetime, LT95) were measured. The results are shown in Table 1. 
     Further, the CIE1931 chromaticity coordinates (CIEx and CIEy) of the resulting organic EL device at the time when a voltage was applied thereto such that the current density became 10 mA/cm 2 , were determined from a spectral radiance spectrum measured by means of a spectral radiance meter CS-1000 (manufactured by Konica Minolta, Inc.). The results are shown in Table 1.
