nols with triphosgene, and the structures of the target compounds were characterized by NMR, IR, and HRMS methods. The fungicidalactivity of the compounds was evaluated at 50 μg/ml concentration, and unsubstituted 6H-benzimidazo-[1,2-c][1,3]benzoxazin-6-one showed 75.1% activity against Sclerotinia sclerotium, which was higher than that of chlorothalonil.
(AIEgens), 2-(2-hydroxybenzene)benzoazole (HBZ)-based molecules are widely applied in organic light emitting diodes, white-light emitters, chemosensors and bioimaging materials. However, there are few reports on the photoresponsive properties of HBZ-based AIEgens. In this work, three HBZ-based AIEgens 2-(2-hydroxy-3-methylphenyl)benzothiazole (1), 2-(2-hydroxy-3-methylphenyl)benzoxazole (2), and 2-(2-hy
