Platinum(II) compounds were synthesized with both chelate cyclometalated ligands and chelate diphosphine ligands. The cyclometalated ligands include phenylpyridine and a benzothiophene-containing ligand. The three new benzothiophene compounds were characterized by nuclear magnetic resonance (NMR) spectroscopy, high-resolution mass spectrometry (HR-MS), and photophysical measurements. In the case of one compound, , the structure was determined by single crystal X-ray diffraction. The structural coherence of the noncrystalline emissive solid state was measured by X-ray total scattering real space pair distribution function analysis. Quantum yield values of all of the platinum compounds measured in the solid state and in PMMA films were much greater than in solution.
铂(II)化合物是通过螯合环金属化配体和螯合二膦配体合成的。环金属化配体包括苯基吡啶和含苯并噻吩的配体。这三种新型苯并噻吩化合物通过核磁共振(NMR)光谱、高分辨率质谱(HR-MS)和光物理测量进行了表征。对于其中一种化合物,其结构通过单晶X射线衍射确定。通过X射线全散射实空间对分布函数分析测量了非晶态发光固态的结构相干性。在固态和聚甲基丙烯酸甲酯(PMMA)薄膜中测量的所有铂化合物的量子产率值远高于在溶液中的值。
