设计合成了两种代数的外围带有羧基、内核为 9,10-二苯基蒽的聚苯醚型树状分子. 分别利用紫外-可见光谱(UV-Vis)、红外光谱(FT-IR)和原子力显微镜(AFM)研究了两种代数的树状分子与聚 4-乙烯基吡啶的交替沉积. 研究表明, 这种将发色团引入多层膜的方法有效地防止了脱附. 同时, 荧光光谱的研究证明, 树状分子可以防止发色团在薄膜中的聚集, 增大树状分子的代数可以增强单个发色团的荧光强度, 这为发光材料薄膜的设计提供了新的思路.
Two algebraic polyphenylene ether dendrimers with carboxyl groups and 9,10-diphenylanthracene nucleus were designed and synthesized. Their structures were characterized by UV-Vis, FT-IR, And atomic force microscopy (AFM) were used to study the alternating deposition of two algebraic dendrimers with poly (4-vinylpyridine). The results show that the introduction of chromophore into the multilayers can effectively prevent the desorption. At the same time, Fluorescence spectroscopy studies have shown that dendrimers can prevent the aggregation of chromophores in the film. Increasing the algebra of dendrimers can enhance the fluorescence intensity of a single chromophore, which provides a new idea for the design of luminescent materials.
