Paper Abstract

In order to obtain the polydiacetylenes with aromatic substituents directly bound to the polymer backbone, many of unsymmetrical diacetylene derivatives with aromatic rings at one side and carbazolylmethyl at the other side of diacetylene moiety have been synthesized. Among them, 1-(3,5-bis(trifluoromethyl)phenyl)-5- (N-carbazolyl)-1,3--pentadiyne (DFCP) was found to be topochemically polymerized with complete conversion into the polymer single crystals. Spectroscopies and X- ray crystal structure analysis revealed that the fr-conjugation between the polymer backbone and the phenyl ring of this polymer are in the similar extent to those of the so-far prepared poly(diphenyldiacetylene)s in spit çf mono- aromatic-substituted polydiacetylene. Nearly the same magnitude of as the largest reported for polydiacetylenes was evaluated from third harmonic generation.
