Abstract:
A triazine compound of the formula: wherein Ar, Arâ€² and Arâ€³ are single or multiple, fused and/or unfused ring moieties, which moieties are aromatic or are selected from 3-pyridyl, 2-naphthyl and 3-quinolyl, which are conjugated to the triazine core and are the same or different;each of R1, R1â€², R1â€³ to Rn, Rnâ€², Rnâ€³, which may be the same or different, is an elongated flexible, aliphatic or aryl-substituted aliphatic chain which imparts liquid-crystalline or columnar crystalline properties to the compound or mixtures of the compounds; and â€”(R1, . . . , Rn), â€”(R1â€², . . . , Rnâ€²), and â€”(R1â€³, . . . , Rnâ€³) indicate that there are up to n, nâ€² and nâ€³ substituent groups R on respective Ar, Arâ€², Arâ€³ moieties, where n, nâ€² and nâ€³ are integers which do not exceed a number of available substituent positions on the respective Ar, Arâ€², Arâ€³ moieties, wherein each of R1, R1â€², R1â€³ to Rn, Rnâ€², Rnâ€³ is independently selected from alkenyl, alkenyloxy, alkenylthio, alkenylamino, alkenyloxycarbonyl, and alkenyl equivalents of acyl, acyloxy, acylthio, and acylamino, where the alkenyl moieties may include further aromatic moieties.
