摘要

They did not show a cholesteric mesophase by themselves, but their 1: l mixture with other cholesteryl arylpropanoates showed cholesteric mesophases near room temperature. The average orientations of the two types of carbazolyl groups in the quasinematic layer were determined by circular dichroism and circularly polarized fluorescence spectroscopy. Their fluorescence spectra showed a monomer fluorescence with a small contribution of ...
