Abstract

We have synthesized liquid crystalline poly (p-phenylene) [LC-PPP] derivatives by introducing liquid crystalline groups into side chains. Addition of a small amount of binaphthyl derivatives as chiral dopants to LC-PPPs gave rise to chiral nematic LC phase. The cast films composed of the LC-PPPs and chiral dopants showed Cotton effects in not only CD spectra but also circularly polarized fluorescence spectra. This implies that the present polymeric systems might be promising candidates for chiral luminescent plastics.
