A series of 1,3,5-phenylene-based rigid dendritic porphyrins were synthesized by Suzuki coupling between a porphyrin core and dendron units. The intramolecular energy transfer was studied by absorption and fluorescence spectroscopies. The encapsulation of the porphyrin core within the 1,3,5-phenylene dendron units was found to provide highly efficient energy transfer from the dendron units to the porphyrin
通过卟啉核心和树枝状单元之间的 Suzuki 耦合合成了一系列基于 1,3,5-亚苯基的刚性树枝状卟啉。通过吸收和荧光光谱研究分子内能量转移。发现卟啉核在 1,3,5-亚苯基树枝状单元内的封装提供了从树枝状单元到卟啉核的高效能量转移。树枝状楔形结构影响能量传递效率。1,3,5-亚苯基刚性树枝状单元作为高效的光捕获天线。这些树突状卟啉也被作为 C(60) 宿主和选择性底物氧化催化剂进行了检查。第二代 1,3,5-亚苯基树枝状单元与卟啉核心的连接使得 C(60) 在甲苯中稳定包含在内。此外,
