A STUDY OF PHOTOCHEMICAL REACTION FOR CBr4-DIPHENYLAMINE IMAGING SYSTEM

doi:10.7517/j.issn.1674-0475.1987.02.31

Abstract

Abstract: The photochemical reaction of free radical lightsensitive system CBr₄-DPA (Diphenylami-ne) is reported. The rate of the photolysis of CBr₄ is decreased with the increasing wavelength in 250-400 nm. When CBr₄-DPA system is radiated upon 254, 284 and 333 nm, which correspond to the maximum absorption wavelengths of CBr₄, DPA, and CBr₄-DPA charge transfer complex, respectively, the maximum rate of photochemical reaction is generated at 333 nm. This shows that the main lightsensitive componant, in the exciting stage, is ground state charge transfer complex consisting of CBr₄ and DPA instead of CBr₄ or DPA.

Key words: free radical image formation, spectral response, charge transfer complex, photolysis, carbon tetrabromide, diphenylamine
