Abstract

The effect of heat treatment at 60-70°C has been studied for merocyanine (MS)-Cd arachidate mixed Langmuir-Blodgett (LB) films. MS chromophores are found to be reorganized by the heat treatments to form a novel phase of a redshifted band with spectra sharper than those of the J-band in the as-deposited films. The reorganization of MS seems to be closely related with the mobility of alkyl chains in the LB system, suggesting that the mild heat treatments will introduce another possible method of modifying the properties of films.
