对10个叶绿素衍生物的合成方法进行了研究，在一定的温度(43.5℃)和丙酮的协同作用下，植物脱镁叶绿素a可转换紫细菌RS601光合反应中心的细菌脱镁叶绿素，光化学活性为对照的71.4%，光化学活性的下降与替代色素的变化无对应关系，替代后降低了Bphe^-/Bphe和QA^-/QA电对之间的电子传递速率。

Ten chlorophyll derivatives were synthesized and five of them were reported for the first time. In the presence of acetone and an excess of exogenous plant pheophytins, bacteriopheophytins in the reaction centers from Phodobacter sphaeroides RS601 were replaced by the pheophytins at sites HA and HB. When incubated at 43.5℃ for 60min, the photochemical activities of the pheophytin reaction centers are 71.4% of the control. The electron transfer rate of Bphe^-/Bphe(phe^- /phe) and QA^-/QA was decreased.
