研究了不同活性分子 (半花菁和氐盐 )混合聚集体的形成以及紫外光照射对 L B交替多层膜光致荧光 (PL)特性的影响。在半花菁和氐盐混合的 L B膜中 ,由于不同分子间较强的相互作用使混合膜的荧光光谱较纯半花菁和氐盐分子膜分别发生了蓝移和红移。利用紫外光照射可以使分子的聚集体部分分解甚至破坏分子的结构 ,导致光致荧光强度明显减弱 The formation of mixed aggregates of different active molecules (hemicyanine and halite) and the effect of UV irradiation on the photoluminescence (PL) properties of L B alternating multilayer films were investigated. In the mixture of hemocyanine and phosphonium salt, the fluorescence spectra of the hybrid membranes were blue-shifted and red-shifted, respectively, compared with the pure hemicyanine and halophile molecular membranes due to the strong interaction between different molecules. The use of ultraviolet light can make the molecular part of the aggregate decomposition or even destroy the structure of the molecule, resulting in significantly reduced fluorescence intensity
