Patent ID: 8277775

Claim:
A molecule having the formula I, wherein: n is 1, 2, 3, 4, 5, 6, 7, or 8; and wherein: L represents a chain comprising 1-20 units, the units selected from the group consisting of: —(CH 2 )—, —CH═CH—, —C≡C—, —NR—, —O—, —S—, —C(O)—, —C(S)—, —C(O)NH—, —NHC(O)—, and a five or six member, carbocyclic or heterocyclic, aromatic or saturated or unsaturated non-aromatic ring, each ring being unsubstituted or substituted with one or more alkyl, aryl, alkoxy, or aryloxy substituent; R represents H, an alkyl group, a carbocyclic aryl group, or a heterocyclic aryl group; Y represents the following formula: A represents H, OH, alkyl, O-alkyl, a halide, or one of the following structures: X represents O or S; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , and R 7 independently represent hydrogen, alkyl, phenyl, alkoxy, or carboalkoxy; or R 1 and R 2 , R 2 and R 3 , R 5 and R 6 , or R 6 and R 7 represent benzo; provided that one of R 1 -R 7 or Q represents a bond to L; Q is fluoro, alkyl, alkoxy, aryloxy, or alkynyl; alkyl and alkoxy groups are unbranched, saturated, and have 1-4 carbon atoms; aryl groups and aryl groups of aryloxy can be either carbocyclic aryl or heterocyclic aryl; carbocyclic aryl groups have a total of 6-20 carbon atoms, including carbon atoms of substituents; heterocyclic aryl groups have a total of 5-20 carbon atoms, including carbon atoms of substituents; carboalkoxy groups are alkyl esters of a carboxylic acid wherein alkyl groups are as defined above; each alkyl, aryl, alkoxy, aryloxy, benzo, and carboalkoxy, independently, may be unsubstituted or substituted with one or more substituent; alkyl substituents are halo, hydroxyl, amino, or aryl; aryl substituents are halo, hydroxyl, amino, alkyl, aryl, nitro, or carboxyl; and halo substituents are fluoro or chloro.
