  A naphthopyran compound represented by the formula B 1 and B 2 may include a phenyl, naphthyl, or heterocyclic aromatic group, or may combine to form one or more aromatic rings. B 1 and B 2 may further include one or more substituents. R a may include an alkyl, polycycloalkyl, alkenyl, polyalkenyl, haloalkyl, perhaloalkyl, alkynyl, polyalkynyl, hydroxyalkynyl, polyhydroxyalkynyl; or (C 3-20 )cycloalkyl group. R b and R c may include hydrogen or alkyl groups, or may combine to form a saturated heterocyclic group, or together with an adjacent phenyl group may form a julolidinyl group. R 3 , R 4 , R 5 , R 6 , and R 10 may include 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 , or —NR b R c ; or any two or more may combine to form a cyclic group. R 7 is a mesogenic group. And the naphthopyran, which may be referred to as a dichroic-photochromic compound, may be incorporated into an optical article.

  A new class of phototropic liquid crystal mixture comprises a liquid crystal host and one or more photodichroic dyes, wherein exposure of the mixture to an activating light causes a light-induced increase in order parameter of the mixture. In some examples, in the absence of the activating light, the phototropic mixture has a lower order parameter than the liquid crystal host, while in the presence of activating light, the phototropic mixture has a higher order parameter than the liquid crystal host. In some examples, upon exposure to the activating light, the phototropic mixture undergoes a phase transition from a material with a lower order to a material with higher liquid crystalline order. In some examples, activating light causes the mixture to transition from an isotropic phase to a nematic phase, from an isotropic phase to a cholesteric phase or form a nematic phase to a smectic phase.

  A naphthopyran compound represented by the formula B 1 and B 2 are selected independently from the group consisting of a phenyl, naphthyl, or heterocyclic aromatic group, or may combine to form one or more aromatic rings. B 1 and B 2 may further include one or more substituents. R 3 , R 4 , R 5 , R 6 , and R 16 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 , or —NR b R c ; or wherein R 5 and R 6 combine to form a cyclic group. R a may include an alkyl, polycycloalkyl, alkenyl, polyalkenyl, haloalkyl, perhaloalkyl, alkynyl, polyalkynyl, hydroxyalkynyl, polyhydroxyalkynyl; or (C 3-20 )cycloalkyl group.
