THE PHOTO-ISOMERIZATION OF CIS-AZOBENZENE - A CHANNEL ELECTRODE STUDY
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....

description | 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 φ = 0.21. © 1992. |
