Abstract

Abstract: A comparison has been made of the effects of the cholesteric and isotropic phases of a 59.5/15.6/24.9 (w/w/w) mixture of cholesteryl oleate/cholesteryl nonanoate/cholesteryl chloride (CM) and of the nematic and smectic phases of trans, trans-4'-n-butylbicyclohexyl-4- carbonitrile (BCCN) on the dynamics of intramolecular fluorescence quenching in several a, w-bis (1-pyreny1) alkanes (PnP). It is demonstrated that whereas the quenching activation ...
