摘要

利用激光光解时间分辨吸收方法，对蚕砂叶绿素中提取的焦脱镁叶绿酸−a 的光化学性质进行了初步的研究。发现，该化合物在实验检测的波长范围内都有较强的吸收，且能产生较高量子产额的三重激发态。进而讨论它作为光活化农药的可能性。

Abstract

By use of time-resolved laser flash photolysis techniques, a preliminary study of the photochemical characters of pyrophaeophorbide-a derived from chlorophyll in silkworm excrement has been completed. It is found that these compounds have strong absorbance in all wavelength ranges under investigation, and produce excited triplet state with high quantum yields. Discussions were made on possible applications of the pyrophaeophorbide-a as photoactivated pesticide.
