摘要
A highly selective colorimetric chemosensor for Hg2+ based on 1,2-diaminoanthraquinone was investigated. 1,2-Diaminoanthraquinone showed color change only with Hg2+, but it showed no significant changes upon addition of other metal ions such as Fe3+, Na+, mg(2+), pb(2+), cd(2+) Ni2+, Cu2+ and Zn2+. The solvatochromic responses of the 1,2diaminoanthraquinone in several solvents of widely different polarities were measured; positive solvatochromism, with a large bathochromic shift, was observed from toluene to DMSO.
