Synthesis of a polymerizable discotic liquid crystalline compound with a 1,3,5-triazine core

Polymerizable 1,3,5-triazine derivatives were prepared, where diphenyldiacetylenic groups were connected to a triazine ring via secondary amino or ether linkages. The compound with secondary amino linkages and pheripheral octyloxy tails exhibited a hexagonal columnar mesophase, showing that intermolecular hydrogen bonding played a key role in molecular ordering. It was polymerized in the hexagonal columnar phase by UV irradiation, yielding the polymer with an ordered structure.
