Aggregation-induced emission and solid fluorescence of fluorescein derivatives was written by Feng, Shumin;Gong, Shengyi;Feng, Guoqiang. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2020.Formula: C20H10Cl2O5 This article mentions the following:
We report herein for the first time that the aggregation-induced emission and strong solid fluorescence of fluorescein derivatives can be realized by slightly modifying their structure, which provides a new option for AIEgens and solid fluorescent materials. In the experiment, the researchers used many compounds, for example, 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0Formula: C20H10Cl2O5).
2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0) belongs to benzofurans derivatives. Benzofuran is the “”parent”” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antioxidant, antitubercular, antiplasmodial, insecticidal.Formula: C20H10Cl2O5
