Web1. máj 2012 · The impacts of Au–thiolate bonding on the near infrared (IR) luminescence of Au nanoclusters are studied by designing two types of monolayer reactions. Firstly, 1,4-dithiol durene (durene-DT) is reacted with Au 25 monolayer protected clusters (MPCs) stabilized by phenylethanethiolate (PhC2S) ligands. Upon the addition of durene-DT, the … WebPhenylethanethiolate monolayer-protected Au38 and Au140 nanoclusters were modified by ligand place exchange with a series of thiolated peptides. The peptides were homooligomers based on the α-aminoisobutyiric acid unit. The effects of changing the peptide concentration and the peptide length in the capping monolayer were studied by differential pulse … unleashed tv app
