设计合成确切结构的异官能基笼型倍半硅氧烷一直是国际性的研究热点问题.用“自下而上”的方法,以半笼型结构倍半硅氧烷为模板,成功地制备出具有Janus结构的四乙烯基四氨基苯基、四乙烯基四苯基异官能基笼型倍半硅氧烷.并且,产物在一些极性溶剂(如四氢呋喃、氯仿及二甲基亚砜)中有较好的溶解性,为其衍生化及应用提供了保证.对所制备的异官能基笼型倍半硅氧烷进行了全面的表征分析,证明其具有Janus异官结构特征及完整的笼型结构.紫外可见及荧光发射光谱证实了倍半硅氧烷笼型结构的电子携带及传输作用,反过来证明其具有完整的笼型结构,同时也为其在有机光电材料中应用提供可能.提供了一类通用合成方法,拓宽了倍半硅氧烷功能单体的种类,并拓展了其应用范围.
Design and synthesis of the exact structure of non-functional cage s-silsesquioxane has been an international research hot issue. “Bottom-up ” approach to the semi-cage structure silsesquioxane as a template, the success Tetravinyltetraaminophenyl and tetravinyltetraphenylisofunctional cage silsesquioxane with Janus structure were prepared, and the products were prepared in some polar solvents such as tetrahydrofuran, chloroform and dimethylsulfoxide Sulfone), which provided a guarantee for its derivatization and application.A comprehensive characterization of the isoconomer-based cage silsesquioxane was carried out, and it was proved that it possessed the characteristics of Janus and Complete cage structure.Ultraviolet-visible and fluorescence emission spectra confirmed the electron-carrying and transporting effect of the silsesquioxane cage structure, which in turn proves that it has a complete cage structure, but also for its application in organic optoelectronic materials Provides a possibility to provide a general class of synthesis methods that broaden the types of silsesquioxane functional monomers and expand their range of applications.
