摘　　要：用光度法测定了桥链冠醚卟啉与Ｃｏ２＋、Ｃｕ２＋配位反应的速率常数、活化能及热力学参数．结果表明：桥链冠醚卟啉与Ｃｏ２＋配位反应活化能Ｅａ较大，△Ｈ＞０；而与Ｃｕ２＋配位反应Ｅｓ较小，且△Ｈ＝０；桥链冠醚钴卟啉的ＥＳＲ谱表明它具有载氧能力．The rate constant, activation energy and some thermodynamic parameters on the coordinate reaction of bridged crowned porphyrin with Co2+ and Cu2+ were determined by spectrometric methods. Experiment results shown the activation energy of coordinate reaction on Co2+ with BCPP(△H>0) is greater than Cu2+ with BCPP(△H=0). ESR spectra on CoBCPP revealed that this complex has an ability of carrying oxygen.
