Diaminoanthraquinone-linked polyazamacrocycles: efficient and simple colorimetric sensor for lead ion in aqueous solution

Org Lett. 2009 Feb 19;11(4):987-90. doi: 10.1021/ol802926m.

Abstract

A new colorimetric molecular sensor based on a 1,8-diaminoanthraquinone signaling subunit exhibits efficient binding for lead ion in water and allows naked-eye detection.
