Abstract

CO2 is fixed into benzophenone using poly(p-phenylene) as a photocatalyst and triethylamine as an electron donor under visible light irradiation. The reaction was enhanced by the addition of onium cation with soft character. The enhanced formation of the radical anion and the dianion species in poly(p-phenylene) by sodium reduction was confirmed by the cation addition. The role of the anion species formed in the photocatalytic system is discussed as the electron pool for the photofixation.
