Abstract
A homoleptic Cu(I) coordination complex bearing N^N-bischelating functionalised biquinoline (BQCOOTEG) ligand and weakly coordinating counterions, BF4 or ClO4 respectively, was designed, synthesized and characterized. Hydrophilic tetraethyleneglycol chains functionalizing the ligands help water solubility of these compounds, that show aggregation in water with increasing concentration. Self-assembly behaviour in water was investigated by accurate 1H NMR and UV–Vis-NIR absorption studies, supported by computational studies, highlighting the influence of counterion-metal distance in tuning NIR absorbance of the complex.File in questo prodotto:
