hypochlorite (ClO − ). Electron deficient carbon–carbondoublebond and acidic proton were introduced to regulate the performance of two fluorescent molecules. Both L1 and L2 displayed high selectivity and sensitivity, low detection limit (28.2, 52.0 nM), fast response time and visible color change after addition of HSO 3 − or ClO − . Different techniques including 1 H NMR analysis, high-resolution mass spectrometry

Condensation of 3-cyano-7-diethylamino-N-ethoxycarbonyl-iminocoumarin with various hydrazides as N-nucleophiles gave a new series of 2-oxo-2H-1-benzopyrano[2,3-d]pyrimidines bearing an acylhydrazino fragment in the 4-position. The structures of the products obtained were characterized using IR, 1H NMR, 13C NMR and elemental analysis. The optical properties were reported for three of these compounds
