1,3,5-Triarylpent-2-en-1,5-diones for the colorimetric sensing of the mercuric cation

Chem Commun (Camb). 2001 Nov 7:(21):2262-3. doi: 10.1039/b106941c.

Abstract

The 1,3,5-triarylpent-2-en-1,5-dione group selectively undergoes cyclisation and changes its colour from yellow to magenta upon coordination of Hg2+ on a remote site.
