•This complex could be used as a phosphorescent “turn-on” chemosensor for Hg2+.•The detection limit is down to 10-7 M range.•An AND logic gate has been developed with Hg2+ and acetonitrile as inputs.
A cyclometalated iridium(III) complex Ir(dpci)2(cbd) (Ir1, dpciH = 3, 4-diphenylcinnoline, cbd = N-carbazolylcarbodithioate) has been prepared and confirmed by 1H NMR, 13C NMR, MS, and crystal data. Ir1 could be used as a phosphorescent chemosensor for Hg2 + and acetonitrile (ACN). Upon addition of aqueous Hg2 +, the ACN solution of Ir1 gave a visual color change and significant phosphorescent enhancing (130-fold) at 580 nm (OFF–ON). Ir1 has been developed as an AND logic gate with Hg2 + and ACN as inputs. The dissociation of Ir1 and coordination with ACN are response for the sensor process.
