4,4′-(1,4-苯撑)-双-(N-甲基-2,6-二苯基)双吡啶盐与四苯基磺酸锌卟啉相互作用研究

Studies on the Interaction Between 4,4'-(1,4-Phenylene)-bis-(N-Methyl-2,6-Diphenyl)Pyridinium Salts and Tetraphenylsulfonic Porphine Zinc

在可见光照射下,水溶性的四苯基磺酸锌卟啉(ZnTPPS),当有还原剂存在时,可使连吡啶双盐如甲基紫精MV^(2+)还原成一价甲基紫精MV·+。在铂催化剂存在下,MV·+又可将H_(2)O还原成H_(2)。由于H_(2)是一个重要能源,此反应近年来深受重视。

4,4'-(1,4-Phenylene)-bis-(N-methyl-2,6-diphenyl)pyridinium salts(PMDP)and tetraphenyl sulfonic porphine zinc(ZnTPPS)were prepared and the interactions between.PMDP and ZnTPPS have been investigated preliminary by electron or fluorescence spectroscopic method.It has been found that in ground state the Complexes will form between the molecules of PMDP and ZnTPPS,and in excited state the fluorescence of ZnTPPS will be quenched by PMDP.
