Abstract
A compound of the present invention is a triazine compound of the general formula: Ar, Ar′ and Ar″ are aromatic moieties which are conjugated to the triazine core and are the same or different. Each of R1, R1′, R1″ to Rn, Rn′, Rn″, which may be the same or different, is an elongated flexible, at least partly aliphatic chain such as to impart liquid-crystalline or columnar crystalline properties to the compound or its mixtures. —(R1, . . . , Rn), —(R1′, . . . , Rn′) and —(R1″, . . . , Rn″) indicate that there are up to n, n′ and n″ substituent groups R on respective Ar, Ar′, Ar″ moieties, where n, n′ and n″ are integers which do not exceed a number of available substituent positions on the respective Ar, Ar′, Ar″ moieties.
