The solvent-dependent photophysical studies suggest that the emission of AAT is sensitive to environment polarity due to which interesting changes in the colored emission may be observed owing to the charge transfer (CT) processes. AAT also self-assembles to tree-like branched morphologies and produce, a greenish emission inside the cells when imaged after short interval (15 mins) of incubation while a red fluorescence could be noted after 24 h. Interestingly, AAT also produce differential emission inside mouse normal cells as compared to its cancer cell lines since it possess anticancer activity. The experimental observations were also validated theoretically via computational modeling.falseAnticancer properties | Cell imaging | Charge transfer | Computational modeling | Fluorescent dye | Self-assemblyArticlehttps://www.scopus.com/inward/record.uri?eid=2-s2.0-85151455872&doi=10.1002%2fasia.202300044&partnerID=40&md5=d82c9296a0a8534ce2c01e42b6b155aa1861471X2 May 20231e202300044arJournal1WOS:000961796300001
