为改善功能分了的特性,提出一种基于金属纳米粒子-偶氮染料复合物共掺杂超分子结构功能材料的设计新方法.并依照此方法制备出复合材料,观测了其显微结构,测量了其紫外-可见光吸收,研究了该超分子结构复合体系的荧光特性.实验发现,由于金属银纳米粒子的掺杂,使得超分子结构复合体系中功能分子甲基橙在溶液态体系的荧光强度增强近5倍,而在两种不同结构(共混结构和包覆结构)的薄膜态超分子结构体系中,其荧光强度分别被猝灭15%和20%.研究结果表明,复合膜中采用超分子结构完全能够改善功能分子的特性.
In order to improve the characteristics of functional subdivision, a new design method based on metal nanoparticle-azo dye composite co-doped functional material of supramolecular structure was proposed. The composite material was prepared according to this method and the microstructure, The UV-Vis absorption was measured and the fluorescence characteristics of the supramolecular composite were studied. It was found that due to the doping of metal silver nanoparticles, the fluorescence of the functional molecule methyl orange in the supramolecular complex system Its intensity increased by nearly 5 times, but in the film-like supramolecular structure system with two different structures (blend structure and cladding structure), its fluorescence intensity was quenched by 15% and 20% respectively. The results show that in the composite membrane The use of supramolecular structures can completely improve the functional properties of molecules.
