Substitution of the chlorido ligand of cyclometalated [Pt (5-R-1,3-di(2-pyridyl) benzene)Cl] (R = methyl, mesityl, 2-thienyl, or 4-diphenylamino-phenyl) by 4-phenylthiazole-2-thiolate leads to related thiolato complexes, which were fully characterized. Their photophysical properties were determined in degassed dichloromethane solution. The emission color of the novel complexes can be easily tuned by the nature of the substituents on the terdentate ligand, as is the case for the parent chlorido complexes. Their luminescence Quantum Yield is high, with that of the compounds with the 2-thienyl or 4-diphenylamino-phenyl substituents being much higher than that of the related chloride complexes. The platinum complex with the cyclometalated 5-(2-thienyl)-1,3-di(2-pyridyl) benzene was used as the emitter for the fabrication of a yellow solution-processable OLED.
用4-苯基噻唑-2-硫醇盐取代环金属化的[Pt(5-R-1,3-二(2-吡啶基)苯)Cl](R = 甲基、均三甲苯基、2-噻吩基或4-二苯胺基苯基)中的氯配体，得到了相关的硫醇盐配合物，并对其进行了全面表征。在脱气二氯甲烷溶液中测定了它们的光物理性质。与母体氯配合物一样，新型配合物的发射颜色可以通过三齿配体上取代基的性质轻松调节。它们的发光量子产率很高，其中具有2-噻吩基或4-二苯胺基苯基取代基的化合物的发光量子产率远高于相关的氯化物配合物。用环金属化的5-(2-噻吩基)-1,3-二(2-吡啶基)苯的铂配合物作为发光体，制备了一种可溶液加工的黄色OLED。
