摘要：

Anion sensing by optical sensors has gained considerable attention. Perchlorate ions readily exist in water medium. Sensing of ClO4- in water and living cells is still poorly studied. In this work, we demonstrate an efficient strategy for sensing of ClO4- in water and imaging ClO4- with red emission in cells by using a facilely synthesized cationic cyclometalated iridium(III) complex. Taking advantage of aggregation induced emission enhancement (AIEE), this iridium(III)-based sensor with weak emission in water displayed clear emission enhancement in presence of ClO4-. It is also demonstrated that the sensing process in water would not be interfered by Hg2+ which is capable of quenching emission of the sensor in THF. (C) 2016 Elsevier B.V. All rights reserved.
