Zhao, Yuqing published the artcilePolymer immobilization effect on excited state of emitting copper complex: Synthesis, characterization and performance improvement, COA of Formula: C6H4N2, the main research area is copper complex dopant polyvinylpyrrolidone electrospinning nanofiber.
In this effort, the correlation between polymer immobilization effect and excited state of emitting Cu complex was discussed. An electron-pulling diamine ligand having an oxadiazole ring and a F atom was synthesized. Its corresponding Cu(I) complex was synthesized with a phosphorus ligand (PPh3) having obvious steric hindrance as auxiliary ligand. Its geometric structure, electronic transition and photophys. parameters were discussed. A distorted tetrahedral coordination field was adopted by this Cu(I) complex. Its onset electronic transition was confirmed as a charge transfer 1 and suffered from structural relaxation badly. Using electrospinning method, this Cu(I) complex was dispersed and immobilized into a polymer host so that structural relaxation of its excited state could be limited. A systematical comparison between various states of this complex, in solution, in solid state and in fibrous samples, was performed. It was finally confirmed that this polymer matrix served as a promising supporting host, offering a rigid and protective microenvironment for dopant mols. which effectively limited their MLCT structural relaxation and improved their photostability.
