Pyrene-linked triazole-modified homooxacalix[3]arene: a unique C3 symmetry ratiometric fluorescent chemosensor for Pb2+

Org Lett. 2011 Feb 18;13(4):552-5. doi: 10.1021/ol102914t. Epub 2010 Dec 31.

Abstract

A new type of fluorescent chemosensor based on homooxacalix[3]arene was synthesized. The fluorescent sensor was highly selective for Pb(2+) in comparison with other metal ions tested by enhancement of the monomer emission of pyrene. The C(3) symmetric structure of homooxacalix[3]arene has potential application in the development of a new ratiometric fluorescent chemosensor for heavy metal ions.
