The synthesis and photophysical properties of 22 platinum(II) complexes featuring N^N^O-coordinating ligands are described. The complexes have the form Pt(N^N^O-Ln)Cl (n = 1 to 20). The tridentate ligands comprise lateral pyridine and phenolate rings, offering the metal N and O coordination respectively, linked via an imine or hydrazone unit that provides a further, central N atom for coordination
描述了具有N ^ N ^ O-配位配体的22种铂(II)配合物的合成和光物理性质。配合物的形式为Pt(N ^ N ^ O -L n)Cl(n = 1至20)。三齿配体包含侧吡啶和酚盐环,分别提供金属N和O配位,并通过亚胺或单元连接,后者提供另一个中心的N原子进行配位。该前配HL ñ,其中一些先前已经报道了1协调ST行过渡金属离子在其他情况下,是易于被水杨醛的缩合与8-氨基喹啉合成或者席夫碱(以生成亚胺配位体的基于HL 1-4)或与2- hydrazinopyridines(生成腙类前配体HL 5 –20)。在用简单的Pt(II)盐处理配体时,在温和条件下制备Pt(II)配合物。可以通过乙炔化合物使氯化物配体发生复分解,例如制备两种其他形式的Pt(N ^ N ^ O -L n)(– CC–Ar),其中Ar = 3,5-双(三氟甲基)苯基。已经通过X射线衍射表征了九种络合物的固态。基于亚胺的配合物在520
