摘要：
The effect of hydrothermal treatments (HTT) on merocyanine (MS)-Cd arachidate mixed Langmuir-Blodgett (LB) films has been studied. At temperatures ranging from 30 to 90 degrees C, the redshifted J-band in the as-deposited state has been found to reorganize under the condition of 100% relative humidity, forming a new phase of further redshifted bands with spectra sharper than those of the as-deposited J-band. The HTT-induced phase closely resembles that induced by the heat treatment without humidity control, while the occurrence of the latter is limited to 60-70 degrees C. The water content introduced into the LB system during HTT is suggested to play a catalytic role in facilitating the reorganization by its lubricating and/or hydrolyzing effects to soften the film structure.
