Development of a dendritic structure with a gradient-type quantum well potential

给体和受体分子之间的光致电荷转移是一种重要的现象，本文研究了几种给体-受体连接体系。然而，以供体-受体二联体为重复单元的树枝状分子体系的研究还不是很深入。选择咔唑和苯并噻二唑构建了该体系，并建立了合成路线。测定了它们的紫外-可见吸收光谱和荧光光谱。此外，还研究了将富勒烯(受体)包覆到给体类型的树状大分子(咔唑-苯基甲亚胺)中，开发了一种新的给体-受体体系。

Photoinduced charge transfer between donor and acceptor molecules is an important phenomenon, and several donor-acceptor linked systems are studied. However, dendritic systems with a donor-acceptor dyad as a repeating unit was not well studied. Carbazole and benzothiadiazole was chosen to construct this system, and the synthesis approach was established. The UV-vis absorption and fluorescence spectra were measured. Additionally, the encapsulation of fullerene (acceptor) into a donor-type dendrimer (carbazole-phenylazomethine dendrimer with zinc porphyrin core) was studied, and a new donor-acceptor system was developed.
