Abstract

The present paper deals with the photophysical properties of columnar liquid crystals formed by hexakis-(alky1oxy) triphenylenes. Absorption and fluorescence spectra of solutions are analyzed on the basis of quantum chemical calculations performed by the CS-INDO-CI (conformations spectra-intermediate neglect of differential overlap-configuration interaction) methd. the absorption maximum is due to the SO-Sq transition while fluorescence ...
