Recommanded Product: 1762-34-1. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Unusual Photoelectrochemical Properties of Electropolymerized Films of a Triphenylamine-Containing Organic Small Molecule.
The electropolymerized films of poly(L)n on In-Sn oxide (ITO) electrode was prepared by anodic electrooxidation of a CH2Cl2 solution of a triphenylamine-carrying organic mol. L, and were characterized/studied by UV-visible absorption spectroscopy, XPS, x-ray diffraction, electrochem. impedance spectroscopy, cyclic voltammetry and photoelectrochem. measurements. Poly(L)n films show surface-controlled TPA•+1/0 associated quasi-reversible redox and exceptionally high photocurrent generation properties. At a zero external bias potential and under 100 mW/cm2 white light irradiation, a photoelectrochem. device composed of a Poly(L)1-modified ITO as working electode, a Pt disk counter electrode and SCE reference electrode in a 0.1M Na2SO4 aqueous solution exhibited a significant cathode photocurrent d. of 2.2μA/cm2, which could be switched to be anodic and outperform most previously reported mol.-based modified ITO electrodes under similar exptl. conditions. Poly(L)n films offer a number of future perspectives ranging from organic photovoltaic to photoelectrochem. catalysis and sensing.
