Regulation of conjugate rigid plane structures for achieving transformation of fluorescence recognition properties

Abstract

Bisbenzimidazole is an important class of fluorescence molecular probe materials with environmental, clinical and biological systems. Meanwhile, different bisbenzimidazole derivatives due to excellent coordination property and various fluorescence characteristic, were...

Visible Light‐Regulated Ring‐Opening Polymerization of Lactones by Employing Indigo as a Photoacid Catalyst

“…General Methods-Method and Materials: 𝜹-Valerolactone (𝜹-VL; 99%, TCI chemicals) and 𝝐-caprolactone (𝝐-CL; 99%, TCI chemicals) were distilled over CaH 2 under reduced pressure and stored under an argon atmosphere at −20 °C. Dichloromethane (DCM) (>99.5%; water content, <0.001%) was purchased from Sinopharm Chemical Reagent Co., [55][56][57] All other chemicals were obtained from Shanghai Chemical Reagents Co., Ltd. and used as received unless mentioned.…”

“…Other indigo, indirubin and 2‐(1H‐benziMidazol‐2‐yl)−1H‐benziMidazole (DBA) were prepared according to the literature procedure. [ 55–57 ] All other chemicals were obtained from Shanghai Chemical Reagents Co., Ltd. and used as received unless mentioned.…”
