Abstract

Photoelectrochemical stability (to corona charging + light exposition), light stability, electrophotographic and spectral properties of charge transport layers (CTL) on the base of organic photoconductor (OPC) doped polycarbonate (PC-A) layers have been investigated.An influence of electrical current transition and light exposure on CTL was studied with drums of a type “Al-ITO-CGL-CTL”. Charge generation layer (CGL) on the base of titanyl phthalocyanine (TiOPc) was used.Products of photoelectrochemical and photochemical reactions of 4-diethylaminobenzaldehyde N,N-diphenyl-hydrazone (DEH) and triarylamines (TAA) in the layers were investigated with Gas Chromatography-Mass-Spectrometry (GC-MS), Thin Layer Chromatography (TLC) and UV-Vis spectroscopy.It was shown that the photoelectrochemical processes in drums give the same main proucts of OPC's molecules conversion as photochemical processes in the films but in different amounts. An addition of a stabilizer - 2,3,5,6-Tetramethylpyrazine (TMP) leads to more stability of OPC molecules in CTLs and to decreasing of light absorption at wave lengths more than 410 nm These data confirm the earlier done supposition that the minor products with the light absorption at wave lengths more than 410 nm are the base products caused the OPC Drum cyclic fatigue.
