γ-Cyclodextrin-based [2]rotaxane stoppered with gold(i)–ethynyl complexation: phosphorescent sensing for nitroaromatics

Abstract

A [2]rotaxane is assembled by γ-cyclodextrin (γ-CD) with threaded 1,4-diethynylbiphenyl and bulky Au(I)–phosphine stoppers. The phosphorescence of the [2]rotaxane has been observed in aerated aqueous solution and found to be quenched by nitroaromatics due to γ-CD-based co-binding, providing a sensitive approach towards explosive-sensing.
