| Popis: | Anthracenyl(diphenyl)phosphine oxide and dianthracenylphenylphosphine oxide as photoactive compounds have been synthesized. Anthracenyl group of these compounds indicate the multi-functional roles such as an emission component, a photodimerization component, and a leaving group. When the light irradiation was performed under an oxygen atmosphere, photo-oxidative P C bond cleavage to leave the antharacenyl group was observed. Moreover, phosphonyl radical was produced and then P P bond formation to form diphosphane was observed. |
