Abstract: Three new d10 Hg and Au poly-yne and its diyne containing 9-butylcarbazole unit were synthesized by dehydrohalogenation reactions and characterized by 1H NMR, 13C NMR, 31P NMR, FTIR, FAB-MS, UV-Vis, fluorescence and phosphorescence spectroscopies. All the compounds were analytically and spectroscopically characterized to possess a well-defined size and structure. The materials are organic\|soluble and solution-processable. The results show that the organic triplet emission can be harvested by the heavy-atom effect induced by Au and Hg which can efficiently promote the intersystem transition from the S1 singlet excited state to the T1 triplet excited state. The relationship between the T1 energy state and the intersystem transition for the system was discussed. It is envisioned that a structure\|property\|function relationship can be established and valuable insight into the photophysical nature of conjugated materials can be subsequently derived.
