WebApr 14, 2008 · In consequence of the increased steric profile of the Mepy ligand, we find the stoichiometry diminished to 1:1:1, which resulted in theformation of [(Ph 3 P)MepyCu(SCN NCS)Cu(Mepy)(PPh 3)] dimers.TDDFT/CPCM calculations were used to clarify the type of transitions involved in the UV/Vis absorption spectra, and the corresponding experimental ... WebSimple mononuclear Cu(i)-halide complexes, [CuX(PPh3)2(4-Mepy)] (X = Cl−, Br−, I−; PPh3 = triphenylphosphine; 4-Mepy = 4-methylpyridine), were prepared. They exhibit blue light emission, with extremely high photoluminescence quantum yields approaching 100% in …
