Complexation equilibria between copper(II) and thiosalicylic acid. Spectrophotometric determination of copper in non-ferrous alloys

The isomeric effect of mercaptobenzoic acids on the preparation and fluorescence properties of copper nanoclusters

“…1a displays that TA-Cu NCs aggregates have a visible absorption shoulder at 338 nm, which is assigned to the TA-Cu moieties. 9 The absorption peaks over 270−300 nm are assigned for TA. Lack of a surface plasmon resonance absorption peak in the region of 400−700 nm reveals 60 the absence of any large copper nanoparticles in the solutions.…”
