| Abstract: | 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. |
