摘要：
A cyclometalated iridium complex (1) with indolium block was synthesized successfully and then used as a colorimetric probe for bisulfite in CH3CN-HEPES (v/v, 2:98) buffer system with the detection limit as low as 0.15 M. It is interesting that the in situ generated 1-SO3H system demonstrated sequential recognition to Cu2+, along with the solution color recovering from colorless to light-yellow. The apparent solution color changes displayed that the complex I can be used to detect bisulfite and Cu2+ by naked eyes. (C) 2017 Elsevier B.V. All rights reserved.
