The synthesis, structural, electrochemical and photophysical properties of a series of 4,6-diphenyl-2,2′-bipyridine platinum(II) complexes bearing σ-alkynyl ancillary ligands were studied. Absorption bands were observed in UV–Vis absorption spectra (maximum peaks range from 431 to 455nm) and phosphorescence emission maxima varied from 554nm to 577nm. Both the UV absorption and photoluminesence emission...
A class of highly fluorescent and stable carbazole end-capped phenylene ethynylene compounds have been synthesized and characterized. They show high extinction coefficients of absorption (λmaxabs=330–340nm) and quantum yields of fluorescence (λmaxem=393–396nm; Φ F =0.52–0.73) in dichloromethane. The solid state absorptions and emissions are significantly red-shifted from the dilute solution...
