摘要
A highly selective phosphorescent chemosensor for Hg2+ based on the iridium (III) complex Ir(DTBT)(2)(acac) (DTBT = 2-(5-(1,2 dihydroacenaphthylen-5-yl)thiophen-2-yl)benzothiazole, acac = acetylacetone) was synthesized and characterized. Ir(DTBT)(2)(acac) exhibited relatively weak fluorescenceat at about 700 nm. Ir(DTBT)(2)(acac) displayed a dramatic color change from near-infrared to yellow-green with the addition of Hg2+. More significantly, the chemosensor performed "turn-on" phosphorescent responses toward Hg2+. (C) 2016 Elsevier B.V. All rights reserved.
