A novel terpyridine/benzofurazan hybrid fluorophore: metal sensing behavior and application

Dalton Trans. 2011 Mar 14;40(10):2173-6. doi: 10.1039/c0dt01053g. Epub 2010 Nov 18.

Abstract

Terpyridine/benzofurazan conjugation results in a new hybrid fluorophore of the colorimetric sensing ability for Fe(2+) and fluorimetric sensing ability for XII group cations. The improved emission properties and cell imaging ability imply it is a suitable platform to construct a fluorescent sensor for metal imaging in biological systems.
