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.
