| 英文摘要 | A new molecule, (Z)-4-(4-(dimethylamino)benzylidene)-3-methyl-1-(pyridin-2-yl)-1H-pyrazol-5(4H)-one (dmpp), and its novel heteroleptic iridium(III) complex, [(ppy)(2)Ir(dmpp)]PF(6), were synthesized and characterized. Both dmpp and [(ppy)(2)Ir(dmpp)]PF(6) could be used as highly selective and sensitive chemodosimeters for the cyanide anion by the naked eye, owing to the addition of the CN(-) to the vinyl group of dmpp. The addition of CN(-) to a solution of dmpp induced a change in the solution color from yellow to colorless, and to [(ppy)(2)Ir(dmpp)]PF(6) induced a change in the solution color from pink to colorless. Moreover, [(ppy)(2)Ir(dmpp)]PF(6) could also act as a phosphorescent and electrochemical probe of CN(-). The green phosphorescence band at 520 nm and a new irreversible oxidation wave at 0.423 V showed up upon the addition of CN(-), indicating that [(ppy)(2)Ir(dmpp)]PF(6) was an excellent multisignaling chemodosimeter of CN(-). Importantly, the Ir complex-based cyanide chemodosimeter [(ppy)(2)Ir(dmpp)]PF(6) has much easier and faster detection of CN than pure organic molecule dmpp. |
