Abstract:
1. A naphthopyran compound selected from the group consisting of Formula (I), Formula (II), and Formula (III), wherein each X is independently selected from —O—, —S—, and —N(R selected from hydrogen, hydrocarbyl, and substituted hydrocarbyl, each q is independently from 1 to 4; R R B and B′ are each independently selected from, hydrogen, unsubstituted aryl, substituted aryl, unsubstituted heteroaryl, and substituted heteroaryl, or B and B′ taken together form a ring structure selected from unsubstituted fluoren-9-ylidene, substituted fluoren-9-ylidene, saturated spiro-monocyclic hydrocarbon ring, saturated spiro-bicyclic hydrocarbon ring, and spiro-tricyclic hydrocarbon ring; provided that at least one of (i) at least one R wherein: (a) Q wherein the aryl substituents, heteroaryl substituents, cycloalkyl substituents, and heterocycloalkyl substituents are each independently selected from P, liquid crystal mesogens, halogen, poly(C wherein said straight-chain C wherein said straight-chain C (b) c, d, e, and f are each independently chosen from an integer from 1 to 20; and each S said substitutes for the alkylene and haloalkylene are independently selected from C (c) P for each occurrence is independently selected from hydroxy, amino, C (d) d′ is chosen from 1, 2, 3, and 4, and
