A new class of silica-supported chromo-fluorogenic chemosensors for anion recognition based on a selenourea scaffold

Abstract

The first example of a chemosensor (L) containing a selenourea moiety is described here. L is able to colorimetrically sense the presence of CN and S2− in H2O : MeCN (75 : 25, v/v). Moreover, when L is loaded into functionalised mesoporous silica nanoparticles an increase in the selectivity towards S2− occurs via a selective fluorescence response.
