Li, Shigang published the artcileRestricting structural relaxation of a phosphorescent copper emitter via polymer framework: Characterization and performance, Formula: C6H4N2, the main research area is crystal structure copper iodophenylpyridinyloxadiazole phosphine; copper pyridyloxadiazole preparation.
A diamine ligand having an electron-withdrawing oxadiazole in its mol. structure was designed. With the help from an auxiliary ligand, PPh3, its Cu(I) complex was synthesized and analyzed, including single crystal structure, electronic transitions and photophys. features. A distorted tetrahedral coordination field was adopted by this Cu(I) complex which experienced intense geometric distortion. To limit this excited state geometric distortion and consequently improve its emissive performance, this Cu(I) complex was dispersed and immobilized into a polymer rigid framework through electrospinning method. A detailed anal. on the photophys. parameters of solid sample, solution sample and electrospinning fibrous samples suggested that polymer immobilization was highly effective in limiting excited state geometric distortion. Dopant mols. were dispersed and immobilized in polymer’s rigid and protective microenvironment. In this case, their geometric distortion was effectively limited, showing improved photophys. performance, such as emission blue shift, long-lived emissive center and better photostability.
