Schmidhammer, U. et al. published their research in Springer Series in Chemical Physics in 2007 | CAS: 1552-42-7

Crystal violet lactone (cas: 1552-42-7) belongs to benzofurans derivatives. Benzofuran derivatives have shown many biological activities, including antifungal and antimicrobial properties, and acting as antagonists of H3 receptors and angiotensin II. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.Computed Properties of C26H29N3O2

Electron transfer in triarylmethane lactones: from the sub-100 fs regime to solvent control was written by Schmidhammer, U.;Karpiuk, J.;Lochbrunner, S.;Riedle, E.. And the article was included in Springer Series in Chemical Physics in 2007.Computed Properties of C26H29N3O2 This article mentions the following:

The electron transfer in triarylmethane lactones can be as fast as 50 fs exceeding the inertial solvation. Changing the character of the excited state switches to complete solvent control. In the experiment, the researchers used many compounds, for example, Crystal violet lactone (cas: 1552-42-7Computed Properties of C26H29N3O2).
