ELECTRIC FIELD EFFECT ON OPTICAL DICHROISM OF SOME AZODYES DISSOLVED IN COMPENSATED CHOLESTERIC LIQUID CRYSTAL
Journal Title: Analele Universitatii din Bucuresti. Chimie - Year 2009, Vol 18, Issue 1
Abstract
In the paper are presented the results obtained in the study of the optical dichroism of some azodyes dissolved in a compensated mixture of cholesteryl chloride and cholesteryl-nonanoate under the electric field action. The electric field dependence of the order parameter S of the dyes is presented and discussed.
