Abstract
The photoirradiation effect of poly(3-hexylthiophene) (P3HT) were studied under CO{sub 2} atmosphere. P3HT film became soluble by photoirradiation in adequate solvents such as ethanol, CHC1{sub 3}, hexane and CH{sub 3}CN under CO{sub 2} atmosphere as well as O{sub 2} atmosphere. This photosolubilization reaction required higher photon energy than the band gap energy of P3HT, and the photoluminescence intensity of P3HT in solvent decreased under CO{sub 2} atmosphere. The solubilized P3HT had larger band gap energy and shorter effective conjugation length than those of original P3HT, and offered an IR absorption peak indicating formation of calbonyl group. These results suggested that electrons transferred from photoexcited P3HT to CO{sub 2} molecules in the first stage of photoinduced reaction. Salicylic acid was obtained by photoirradiation of P3HT in ethanol solution containing phenol indicating the photocatalysis of P3HT. 9 refs., 8 figs.
