Abstract:
1. A naphthopyran compound represented by the formula (I) wherein B 1 and B 2 are selected independently from the group consisting of (i) a phenyl group, (ii) a naphthyl group, (iii) a heterocyclic aromatic group, and (iv) a combination thereof, or wherein B 1 and B 2 optionally combine to form one or more aromatic rings; wherein B 1 and B 2 are optionally substituted with one or more substitutents selected from the group consisting of halogen, —R a , —OH, —OR a , —SH, —SR a , —SOR a , —SO 2 R a , —NR a R a , —NR b R c , —CN, —NO 2 , —CO—R a , —O—CO—R a , and —CO 2 R a , wherein R a is a linear or branched (C 1-20 ) alkyl, (C 3-20 ) cycloalkyl, (C 4-20 ) polycycloalkyl linear or branched (C 1-20 ) alkenyl, linear or branched (C 1-20 ) polyalkenyl, linear or branched (C 1-20 ) haloalkyl, perhaloalkyl group, linear or branched (C 1-20 ) alkynyl, linear or branched (C 1-20 ) polyalkynyl, linear or branched (C 1-20 ) hydroxyalkynyl, linear or branched (C 1-20 ) polyhydroxyalkynyl; R b and R c are independently selected from the group consisting of hydrogen and linear or branched (C 1-20 ) alkyl groups, or wherein R b and R c combine to form a saturated 5- to 7-member heterocyclic group, or wherein R b and R c together and in combination with an adjacent phenyl group form a julolidinyl group; wherein R 3 , R 4 , R 5 , R 6 , and R 10 are selected independently from the group consisting of hydrogen, halogen, —R a , —OH, —OR a , —O—CO—R a , —CN, —NO 2 , —SO 2 R a , —SOR a , —SH, —SR a , —NH 2 , —NHR a , —NR a R a , and —NR b R c ; or wherein R 5 and R 6 combine to form a cyclic group, and wherein R 7 is a mesogenic group represented by one of the following formulas: wherein R 8 is selected from the group consisting of hydrogen, halogen, —R a , —OH, —OR a , —SH, —SR a , —NH 2 , —NR b R c , —CO—R a , —O—CO—R a , and —CO 2 R a , wherein R 9 is selected from the group consisting of hydrogen, halogen, —R a , —OH, —OR a , —O—CO—R a , —CN, —NO 2 , —SO 2 R a , —SOR a , —SH, —SR a , —NH 2 , —NHR a , —NR a R a , and —NR b R c ; or wherein an R 8 and R 9 combine to form a cyclic group, wherein p is an integer from 0 to 5, wherein m is an integer from 0 to 4, wherein X 1 is a covalent bond, wherein X 2 and X 3 , identical or different from each other, represent a covalent bond or linking unit selected from the group consisting of an ester, —R d —, —O—, —OR d —, —OR d O—, —OCOR d —, —OCOR d O—, —S—, —CH═CH—, —CH═N—, —C≡C—, and —N═N—, wherein R d is a linear or branched (C 1-18 ) alkyl or a linear or branched (C 1-18 )haloalkyl group, and wherein Y is oxygen, nitrogen, or sulfur.
