2-Methylbenzo[b]thiophene (cas: 1195-14-8) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. It is found within the chemical structures of pharmaceutical drugs such as raloxifene, zileuton, sertaconazole, and also BTCP.Formula: C9H8S

Enhanced photoconversion of 1,2-bis(2-methyl-1-benzothiophene-3-yl)perfluorocyclopentene in ionic liquid solutions was written by Soromenho, Mario R. C.;Siopa, Filipa;Afonso, Carlos A. M.;Esperanca, Jose M. S. S.. And the article was included in Journal of Photochemistry and Photobiology, A: Chemistry in 2018.Formula: C9H8S This article mentions the following:

An improved strategy for the photoinduced ring closure conversion of diarylethene, 1,2-bis(2-methyl-1-benzothiophene-3-yl)perfluorocyclopentene (BTF6), in ionic liquid solutions was investigated. The convertibility yield of the photochrome was monitored by UV-vis spectroscopy. Significant improvements of the convertibility yield were achieved in ionic liquid solutions in comparison with conventional organic solvents. These results open the door to the creation of new enriched photochromic systems based on ionic liquids In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8Formula: C9H8S).
