Abstract
Structure sensitivity of the recoil-atom reactions and thermal annealing reactions in α- and β-copper phthalocyanines were studied in detail. Isothermal annealing curves were analyzed by the method of Vand and Primak. Two groups of activation-energy spectra appeared corresponding to two stages of the annealing reactions. Stage I was more sensitive to the crystal structure than Stage II. Stage I could be explained by the exchange reaction, Cu2+(1+,0)*+CuPn4→Cu*Pn4+Cu2+(1+,0), and Stage II by the synthetic reaction, Cu2+(1+,0)*+4 Pn→Cu*Pn4 (Pn denotes a phthalonitrile molecule). From the analysis of the initial retentions in the α and β crystals, hot and thermal processes in the initial recoil reactions could be estimated.
