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 prime -n-butylbicyclohexyl-4-carbonitrile (BCCN) on the dynamics of intramolecular fluorescence quenching in several alpha , omega -bis(1-pyrenyl)alkanes (PnP). It is demonstrated that whereas the quenching activation parameters are independent of chain length (n equals 3, 10, 13, 22) in the isotropic phase of CM, they vary greatly with chain length in cholesteric CM.
