合成了一些具有叔丁基和三苯胺等大体积取代基的新型对称和非对称铂（II）席夫碱配合物，有效地减少了铂（II）席夫碱的聚集或准分子的形成。利用所选择的配合物作为磷光发射材料，制备出了比先前报道的类似物效率更高的黄色发光器件。此外，利用黄、蓝两种发光材料组成的单发射层制备了白光磷光有机发光器件（WOLED）。
Some new symmetric and asymmetric platinum(II) Schiff base complexes with bulky substituents such as tert-butyl and triphenylamino groups have been synthesized which effectively reduced the aggregation or excimer formation. Using selected complexes as phosphorescent emitting materials, yellow light-emitting devices were fabricated with improved efficiency compared with the previously reported analogues. In addition, the phosphorescent white organic light-emitting device (WOLED) was fabricated using a single emissive layer composed of yellow- and blue-emitting materials.
