Rational design of reversibly photochromic molecules with aggregation-induced emission by introducing photoactive thienyl and benzothienyl groups was written by Zhou, Shasha;Guo, Sidan;Liu, Weidong;Yang, Qiaoying;Sun, Huili;Ding, Riqing;Qian, Zhaosheng;Feng, Hui. And the article was included in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices in 2020.Related Products of 113893-08-6 This article mentions the following:

Herein, we proposed a general strategy to design reversible photochromic mols. with solid-state fluorescence by introducing photoactive thienyl and benzothienyl groups into an AIE-active mol. skeleton. The combination of a thienyl or benzothienyl group and a triphenylethene in the right manner enabled the mols. to possess unique aggregation-induced emission properties and reversible photo-controlled changes in color and fluorescence in solid state. Theor. anal. revealed that photo-triggered cyclization and cycloreversion reactions were responsible for the reversible photochromism and photoinduced fluorescence switching, and the enlargement of the conjugation of the introduced photoactive units can significantly promote the cyclization reactions and the photochromic processes. The excellent performance of these photochromic mols. with aggregation-induced emission activity in a photoswitchable patterning paper and multiple encryption of anti-counterfeiting of a banknote demonstrated that they are perfectly suited for surface-involved photo-controlled applications such as information storage and data encryption.
