five platinum (II) complexes based on 2‐phenylpyrimidine ligands have been designed. Pyridine and chloride were used as auxiliary ligands. These complexes exhibit a slightly distorted square‐planar geometry. The nature and position of substituent on the phenyl ring was thoroughly studied. The presence of an electron‐donating substituent on the phenyl ring in the para position of the platinum atom leads
设计了一系列基于2-苯基嘧啶配体的五种铂(II)配合物。吡啶和氯化物用作辅助配体。这些复合体显示出略微扭曲的方平面几何形状。彻底研究了苯环上取代基的性质和位置。铂原子对位苯环上存在一个供电子性取代基,导致最低能量吸收带发生红移,这与HOMO→LUMO跃迁相对应,并允许在脱氧CH 2中获得磷光Cl 2溶液。对于在苯基嘧啶配体的苯环上带有给电子取代基的配合物,所有化合物均以固态发射,并具有明显的红移。
