A dual colorimetric chemosensor based on Schiff base for highly selective and simultaneous recognition of CN? and Sn2+

A new colorimetric chemosensor 2-methoxy-6-{(E)-[(4-methylphenyl)imino] methyl}-4-[(E)-(4-nitrophenyl)diazenyl] phenol (SZ) was designed and synthesized for simultaneous detection of CN? and Sn2+ in MeCN: bis-tris buffer solution. Th
