摘要：
The photo-isomerisation of cis-azobenzene by light of wavelength 432 nm has been investigated by channel electrode voltammetry. In a lithium ethoxide/ethanol medium cis-azobenzene was found to be reduced at a more positive potential (ca. 120 mV) than the trans isomer in the dark at a gold electrode. Quantitative waveshape measurements, with the electrode illuminated, of current-voltage curves for the reduction of the cis isomer as a function of the rate of mass transport, reveal the partial conversion of cis to trans and enable the quantum yield for the cis to trans isomerisation to be found as PHI = 0.21.
