A temperature-sensitive luminescent Ag20 nanocluster templated by carbonate in situ generated from atmospheric CO2 fixation

Abstract

A drum-like Ag20 nanocluster, [(CO32−)@Ag20(SBut)10(DMF)6(NO3)8] (1), has been synthesized by the unexpected carbonate-templated self-assembly of AgNO3 and AgSBut precursor. Structural analysis reveals that 1 contains centrosymmetric drum-like Ag20S10 clusters constructed from two Ag5S5 pentagrams and a Ag10 ring. The CO32− in situ generated from fixation of atmospheric CO2 lies on the center of the cluster and acts as an anion template to direct the formation of 1. Interestingly, bright-green photoluminescence of 1 is switched on when cooled with liquid nitrogen.
