Abstract:
1. A composition comprised of a liquid crystal and a compound having formula (3) wherein: D3 is an electron donor moiety which possesses a negative Hammett constant; C3 is a conjugated bridging moiety which is one aromatic ring; A3 is an electron acceptor moiety; S3 is a liquid crystal compatibilizing moiety; and b′ is an integer wherein D3 is selected from the group consisting of: (a) an atom selected from the group consisting of N, O, S, and P, where the valence of the atom is satisfied by bonding with C3: (b) an atom selected from the group consisting of N, O, S, and P bonded to C3, where the atom also is banded to at least one other moiety to satisfy the valence of the atom; (c) ferrocenyl; (d) azulenyl; and (e) at least one aromatic heterocyclic ring.
