A highly selective bifunctional luminescence probe for potassium and fluoride ions

Org Lett. 2011 May 6;13(9):2172-5. doi: 10.1021/ol200277n. Epub 2011 Apr 12.

Abstract

A novel bifunctional molecule 1 by a combination of 1,3-alternate calix[4]-crown-5 and triarylborane moieties through alkynyl linkers has been designed and synthesized. Compound 1 shows intense fluorescence with a photoluminescence quantum yield of 0.70 in CH(2)Cl(2) solution and can serve as a bifunctional luminescent probe for potassium and fluoride ions with high sensitivity and selectivity.
