Abstract
WE wish to give further results of our work on photoconduction in organic compounds at room temperature. We have already proposed1 that photoconduction in solutions of triphenylamine in benzene and n-hexane requires the absorption of two quanta by the solute. Pilloff and Albrecht have recently shown a similar phenomenon in solutions of N,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD) in 3-methylpentane2. Furthermore, our observations show that the magnitude of the photocurrent can be greatly reduced by changing the solvent from benzene to n-hexane. We have also described the influence of oxygen on the response of the pure solvent3.
