卟啉-酞菁二元化合物分子内的能量传递

Energy Transfer Process in A New Heterodimer Porohyrin Phthalocyanine

研究了新的以哌嗪连接的含卟啉－酞菁双发色团的分子（Ｐｒ－Ｐｃ）的时间分辨荧光光谱并对所得的结果进行了分析和讨论．在光谱数据的基础上结合分子的结构对非极性溶剂中二元化合物分子内的能量传递过程和机制进行了讨论，并算出发色团的空间相对距离为１．８７ｎｍ．

The time resolved fluorescence spectroscopy for a new heterodimer molecule Pr Pc, linked by piperazine is presented.The mechanism of energy transfer process is discussed based on the spectral analysis.Combined with the structure information,the two chromophore distance in nonpolar bath is calculated to be 1 87 nm.
