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