Ligand functionalized copper nanoclusters for versatile applications in catalysis, sensing, bioimaging, and optoelectronics

Abstract

Chemically synthesized copper nanoclusters show colour-tunable emission and can be applied in catalysis, sensing, bioimaging, theranostics, and optoelectronics.

Copper nanoclusters: designed synthesis, structural diversity, and multiplatform applications

“…However, despite the extensive research progress in the field of gold and silver nanoclusters, the studies focusing on the preparation and functionalization of other metals like earth abundant copper is still in its infancy. 13 The problem lies in the difficulty of preparing tiny and stable copper nanoparticles and nanoclusters. Copper being in the same group as gold and silver, shares similar properties and can be taken as a viable alternative to expensive and rare metals.…”

Ascorbic acid stabilised copper nanoclusters as fluorescent sensors for detection of quercetin

“…[12][13][14][15][16] To date, a variety of metal nanoclusters have been successfully prepared through an etching synthesis method, 17 phase transfer synthesis method, 18 microwave-assisted synthesis method, 19 sonochemical synthesis method 20 and photoreduction synthesis method, 21 using Au, Ag, Pt and Cu NCs. [22][23][24][25][26][27] Compared to Ag and Au, Cu is an easily available and low-cost metal. In the meantime, Cu NCs have been employed to detect Hg 2+ , 28 Pb 2+ , 29 Chart 1 Chemical structure of quercetin.…”

“…[2b, 4] Furthermore,t he NCs promise potential applications in catalysis, [5] optoelectronics, [6] energy conversion [7] and bioimaging. [8] Thec oinage metals (Au, Ag and Cu) [3,9] and main group metals [10] have largely been explored for synthesizing NCs comprising tens to hundreds of metal atoms. [11] Thebottom-up approach involving chemical reduction of metal-ligand complexes in solutions is ac ommon and straightforward synthetic strategy for am ajority of the reported noble metal NCs,w here the capping ligands are found to play ac ritical role in controlling the size and structure of NCs.…”
