and 31PNMR spectroscopy, as well as mass spectroscopy. Photophysical properties of the L2Pt(Ar)2, and L2Pt(Ar)(Ar′) complexes were measured, including steady-state absorption, photoluminescence, and photoluminescence quantum yields, in order to understand how attachment of the platinum metal influences the excited state properties of the arylene ligands. This work affirms that CuI catalyzed coupling
反式-L 2 Pt(Ar)Cl,L 2 Pt(Ar)2和L 2 Pt(Ar)(Ar')型Pt(II)配合物的制备(L = PBu 3,Ar =亚芳基)据报道,CuI通过CuI催化了顺式-(PBu 3)2 PtCl 2与芳基-
锡烷的反应。反应在25–60°C进行,产率中等至良好。已证明该反应是与具有多种官能度的苯基-和2-
噻吩基-
锡烷一起发生的,所有得到的Pt-芳基络合物的特征均在于1 H,13 C和31
PNMR光谱以及质谱。测量L 2 Pt(Ar)2和L 2 Pt(Ar)(Ar')配合物的光物理性质,包括稳态吸收,光致发光和光致发光量子产率,以了解
