摘要：

Triazo pigment is a new class of excellent organic photoconductive materials, which is synthesized with tertiary aromatic amines and different couplers. The tertiary aromatic amine is a typical electron donor[1]. After irradiation, the electron-donating ability of excited states becomes stronger than that of ground states, radical pair and radical ions are considered to be key intermediates. In the present work, the light-induced ESR spectra of 3-As-SG under different conditions are investigated. It is verified that an electron-transfer process occurred.
