用Hagihara脱氢卤代法合成了三种新的9,9-二(十六烷基)芴基二聚炔铂(d8)、金和汞(d10)化合物反式- [Pt(Ph)(PEt3)2C≡CRC≡CPt(Ph)(PEt3)2, [(PPh3)AuC≡CRC≡CAu(PPh3)]和[MeHgC≡CRC≡CHgMe] [R=9,9-二(十六烷基)芴基]. 用1H NMR, 13C NMR, 31P NMR, FT-IR, FAB-MS, UV-Vis, 荧光和磷光光谱对其进行了表征. 结果表明, 体系中的铂、金和汞产生的重原子效应可以有效地促进单线激发态S1与三线激发态T1的系间跃迁, 使标题化合物产生有机三线态发光.

New Pt(II), Au(I) and Hg(II) complexes coordinated with 9,9-dihexadecylfluorene-2,7-diace- tylide ligands were synthesized by Hagihara dehydrohalogenation reactions and characterized by 1H, 13C, 31P NMR, FT-IR, FAB-MS, UV-Vis, fluorescence and phosphorescence spectroscopic methods. The results show that the organic triplet emission can be harvested by the heavy atom effect induced by Pt, Au and Hg, which enables efficient intersystem crossing from the singlet excited state S1 to the triplet excited state T1.

Key words: 9,9-dihexadecylfluorene-2,7-diacetylene, Pt(II), Au(I) and Hg(II) coordination compound, synthesis, luminescence, phosphorescence
