通过动力学方法建立了光敏作用中~1O_2被TEMPONE捕捉产生的TAN自由基对时间的函数关系式,据此可求出光敏作用Ⅰ,Ⅱ型机制产生各种活性中间体的相对速率常数.并应用上述公式,结合实验结果,具体求算了3种无酵类光敏剂HA,HB,CP在DMF-H_2O和DMSO-H_2O体系中产生~1O_2,O_2和PS的相对速率常数,进而探讨了苝醒光敏剂的构效关系和光敏机制与溶剂的关系. The kinetic method was used to establish the functional relationship of TAN radical generated by TEMPONE capture to time in photosensitization. Based on these results, the relative rate constants of various active intermediates produced by photo-induced I and II mechanisms were obtained. Using the above formula and the experimental results, the relative rate constants of ~ 1 O 2, O 2 and PS produced by three kinds of unfermented photosensitizers HA, HB and CP in DMF-H 2 O and DMSO-H 2 O systems were calculated. Then the perylene Structure - activity relationship of photosensitizer with photosensitizer and its relationship with solvent.
