A novel kind of dimmer (excimer)-induced-AIE compound 2-phenylisothiazolo[5,4-b]pyridin-3(2H)-one as high selective bisulfite anion probe

An interesting dimmer (excimer)-induced-AIE characteristic of 2-phenylisothiazolo[5,4-b]pyridin-3(2H)-one was observed. By using a ring-opening reaction, we developed a novel fluorescent probe based on sub-micron particles of 2-phenylisothiazolo[5,4-b]pyridin-3(2H)-one in water.
