制备了一种具有C60端基的雪花状锌卟啉树枝状大分子。C60单元的共价连接导致Zn卟啉荧光的显著猝灭，这主要是由于从Zn卟啉核心到C60末端的能量转移。与类似的树枝状结构的能量传递效率的比较表明，树枝状结构大大延迟的能量传递速率。
A snowflake-shaped Zn porphyrin dendrimer with a C60 terminal was prepared. Covalent linkage of the C60 unit results in significant quenching of the Zn porphyrin fluorescence mainly due to energy transfer from the Zn porphyrin core to the C60 terminal. Comparison of the energy-transfer efficiency with similar dendrons indicates that the dendritic structure considerably delays the energy-transfer rate.
