Highly Selective Ratiometric Emission Color Change by Zinc‐Assisted Self‐Assembly Processes

Abstract

Color sense: 2-(Anthracen-9-ylethynyl)-1-methylbenzimidazole (BzIm-An) shows a ratiometric color change in emission from blue to light yellow to green with increasing Zn2+ concentration. The dimeric 3:1 complex [{(BzIm-An)3Zn2+}2] formed at low Zn2+ concentration is converted into the 2:1 complex [(BzIm-An)2Zn2+] at high concentrations of Zn2+.
