| Abstract: | Used Eletron Spin Resonance technic, ESR signals of dyes’positive hole were trapped.The decay of ESR signal of positive holes trapped by cyanine dyes about sensitive systemand supersensitive system were studied, Their decay were the second-order reaction.The rate constants of the decay are k2 = 3.269 × 10-4s-1, k2= 5.589 × 10-5s-1.So, two kindsof positive holes produced by sensitive dyes and supersensitive dyes were distinguished,Gilman’s mechanism of trapping positive hole was confirmed further. |

| Keywords: | ESR positive hole decay kinetics supersensitive mechanism |
