Abstract: A chemosensing ensemble consisting of a carbazole-containing dinuclear zinc(II) complex and chromeazurol S displays colorimetric recognition of oxalate in water at pH 7.0. Upon addition of oxalate, the ensemble solution exhibits a naked eye detectable colour change from blue to yellow. The oxalate sensing process is hardly affected by other dicarboxylates; addition of dicarboxylates such as malonate, succinate, glutarate, adipate, phthalate, isophthalate and terephthalate does not induce significant colour changes.
