Hruzd, Mariia;le Poul, Nicolas;Cordier, Marie;Kahlal, Samia;Saillard, Jean-Yves;Achelle, Sylvain;Gauthier, Sebastien;Robin-le Guen, Francoise research published 《 Luminescent cyclometalated alkynylplatinum(II) complexes with 1,3-di(pyrimidin-2-yl)benzene ligands: synthesis, electrochemistry, photophysics and computational studies》, the research content is summarized as follows. In this article, we report on a series of cyclometalated chloro- and alkynyl-platinum(II) complexes [(Pym2C6H2R)PtX] (1–14; Pym = 2-pyrimidinyl-κN; R = H, OMe, CF3; X = Cl, CCC6H4Y, with Y = H, OMe, CN, CHO, NPh2) bearing various tridentate N-C-N-cyclometalated ligands derived from 1,3-bis(pyrimidin-2-yl)benzene. The X-ray crystal structures of two alkynyl-platinum(II) complexes were determined and other structures were DFT-calculated Electrochem. and DFT-computational studies suggest a ligand-centered reduction on the R1-substituted N-C-N ligand, whereas oxidation likely occurs either on the Pt-phenylacetylide moiety and/or the cyclometalated ligand. In CH2Cl2 solution at room temperature, the complexes show phosphorescent emissions ranging from green to orange, depending on the R1 and R2 substituents on the ligands. In KBr solid state matrix, excluding complexes bearing a trifluoromethyl substituted ligand, all compounds exhibit red emission. The presence of an alkynyl ancillary ligand has limited influence on absorption and emission spectra except in the case of the complex with the strongly electron-donating diphenylamino R2 substituent on the alkynyl ligand, for which a significant red-shift was observed The alkynyl Pt(II) complex with OMe groups as both R1 and R2 substituents shows the best emission quantum yield (0.81 in CH2Cl2 solution) in this series. The full series of DFT calculated band gaps correlated generally well with the electrochem. and absorption data and reasonably model the impact of the substituents on the electronics of these complexes.
