- 論文の詳細を見る
Benzo[1, 2, 3-kl: 4, 5, 6-k'l']bisthioxanthene [1b] was synthesized by the cyclization of 1, 5bis(phenylthio)anthraquinone, which was prepared from benzenethiol and 1, 5-dichloroanthraquinone. The photooxidation of the above red compound [1b] with visible light of 541 nm, gave the colorless endoperoxide [2b]. The photochemical and thermal properties of the endoperoxide [2b] to give [1b] were also investigated.
