Preparation of Porphyrin Thin Films Using the Micelle Disruption Method and Their Photoresponses

Abstract
Thin films of eight different porphyrins were successfully prepared on ITO electrodes by means of the electrolytic micelle disruption (EMD) method. Photoelectrochemical properties of these porphyrin electrodes were investigated in an I 3 -/I - redox solution. The photocurrent quantum yield for the (5, 10, 15, 20-tetraphenylporphyrinato)zinc(II) (ZnTPP) electrode prepared by the EMD method reached 12.6%, which was 20 times greater than that for the ZnTPP electrode prepared by the conventional vacuum sublimation technique.
