Peroxynitrite (ONOO−) is a highly reactive and short-lived oxidant with low content in cells, and plays an important role in biology. Accordingly, developing a rapid, sensitive, and effective detection approach of cellular ONOO− is very meaningful to further study its biological functions. In this work, a new biosensor BQ for the recognition of ONOO− was facilely synthesized by condensation of 2-hydrazinoquinoline and formylated benzothiazole possessing ‘‘ESIPT + AIE” feature. The probe can be used in a wide range of pH value, and display...
