摘要

合成了具有通式[Pd(η3-C3H5)(L)](PF6)的钯(II)配合物，其中L为4,7-二苯基-1,10-菲罗啉(1)、2,9-二甲基-1,10-菲罗啉(2)、2,9-二甲基-4,7-菲罗啉(3)、5-甲基-1,10-菲罗啉(4)、3,4,7,8-四甲基-1,10-菲罗啉(5)和2-(2 ' -吡啶基)喹啉(6)，并利用高分辨率ESI-MS、NMR技术和(6)单晶x射线衍射方法对其进行了表征。此外，还研究了它们的光物理性质。配合物(1)-(6)在绿蓝色区域发射，其中含有甲基取代菲罗啉的配合物在固体状态下具有较高的量子产率(≈14%)。

Synthesis, Characterization and Photophysical Properties of Mixed Ligand (η3-Allyl)palladium(II) Complexes with N,N’Aromatic Diimines

Palladium(II) complexes of the general formula [Pd(η3-C3H5)(L)](PF6), where L is 4,7-diphenyl-1,10-phenanthroline (1), 2,9-dimethyl-1,10-phenanthroline (2), 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (3), 5-methyl-1,10-phenanthroline (4), 3,4,7,8-tetramethyl-1,10-phenanthroline (5), and 2-(2′-pyridyl) quinoxaline (6), were synthesized and characterized using high-resolution ESI-MS, NMR techniques and, in the case of (6), single-crystal X-ray diffraction methods. In addition, their photophysical properties were investigated. Complexes (1)–(6) were emitted in the greenish-blue region, with those containing methyl-substituted phenanthrolines having the higher quantum yield (≈14%) in the solid state.
