A new of colorimetric sensor based on azo-hydrazone compound for recognition of CN− ion

A novel of Chemosensor compound 4-((E)-(2-(2,4-dinitrophenyl) hydrazineylidene) methyl)-2-methoxy-6-((E)-phenyldiazenyl)phenol has designed and synthesized from 2,4-dinitrophenyl hydrazine (E)-4-hydroxy-3-methoxy-5-(phenyldiazenyl)benzaldehyde. This sensor was applied as a colorimetric for recognition cyanide anion in acetonitrile solution. In the presence ion, solution turned bright yellow to red with bathochromic shift 390 nm 555 nm. The limit detection investigated by UV-Vis spectrophotometer that detected 7 mM ion Further, FT-IR, 1H-NMR, 13C-NMR were used confirm structure sensor.
