2-Phenylisoindolin-1-one (cas: 5388-42-1) belongs to indole derivatives. The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades. Moreover, it is known that it controls biofilm formation. However, the role of indole in the cell has not been fully elucidated.Electric Literature of C14H11NO

Twisted intramolecular charge-transfer fluorescence of aromatic amides: conformation of the amide bonds in excited states was written by Azumaya, Isao;Kagechika, Hiroyuki;Fujiwara, Yoshihisa;Itoh, Michiya;Yamaguchi, Kentaro;Shudo, Koichi. And the article was included in Journal of the American Chemical Society in 1991.Electric Literature of C14H11NO This article mentions the following:

The mechanism of the dual fluorescence of benzanilide (I) and N-methylbenzanilide (II) in methylcyclohexane was investigated. The emission at longer wavelength is composed of one component for I (婵?sub>max 477 nm) and of one major component (96%, 婵?sub>max 518 nm) for II. Various substitutions on the aromatic rings permit the study of the F2 fluorescence wavelength and intensity on twisting about the Ar-CO, the Ar-N, and the amide bond (N-CO) itself. Though the ground-state structures of I and II are very different from each other, the structures of the emitting species of both compounds are considered to be similar. Studies on conformationally restricted derivatives showed that the amide bond must be rotated for the emission of longer wavelength. Quant. data indicate that the F2 emissions are generated from excited twisted intramol. charge-transfer (TICT) species with twisted amide bonds. In the experiment, the researchers used many compounds, for example, 2-Phenylisoindolin-1-one (cas: 5388-42-1Electric Literature of C14H11NO).
