Abstract
- Fullerene, C60 photosensitizer was incorporated into poly(Azure A) in the process of electrochemical polymerization from the solution of corresponding dye and fullerene. The synthesized organic layer (PAA_C60/ITO) was characterized by means of cyclic voltammetry, UV-Vis, Raman and X-ray photoelectron spectroscopies. It was shown that PAA_C60/ITO exhibits strong absorption in both UV and Vis regions and that both immobilized photosensitizers, i.e. Azure A and C60, retain their photochemical activity towards 1O2 generation under illumination as tested with 2,3,4,5-tetraphenylcyclopentadienone (TPCPD) singlet oxygen quencher. The electrodeposited photoactive layer composed of two photosensitizers was investigated as a source of 1O2 in the process of α-terpinene oxidation.
