合成了一系列含寡聚芴单元的单核和双核(C~∧N~∧N)型(C~∧N~∧N=6-苯基-2,2′-二联吡啶)环金属化铂配合物,通过元素分析、核磁共振谱、高分辨质谱、紫外-可见光谱、荧光光谱和电化学等方法对配合物结构和光电性质进行了表征.研究结果表明,将具有高三线态能级的寡聚芴单元化学掺杂于[R(C~∧N~∧N)Pt](R=4-[对-(N-正丁基-N-苯基)苯胺基])配合物中,不改变配合物发光机制,各组分之间彼此能够保持相对独立的光谱和电化学性质.在以三聚芴为中间桥联基团而形成的线性双核配合物体系中,分子内存在由三聚芴单元向配合物单元的能量转移过程.

A series of mono-and di-nuclear cyclometalated Pt(II) complexes with oligofluorene units as the secondary ligands and the bridgers have been synthesized and characterized by means of the elemental analysis, NMR, MALTI-ToF MS, UV-vis spectrum, photoluminescent spectrum and electrochemical measurements. The results indicate that the introduction of the oligofluorene units with higher triplet energy levels has no effect on the emission mechanism of the Pt(II) complex. Each component keeps the independent spectroscopic and electrochemical properties relatively. An intramolecular energy transfer from the oligofluorene unit to the complex unit exits in the novel π-conjugated supermolecular system with the linear configuration, exploiting fluorene trimer as the core bridger to link two[R(C~∧ N~∧ N)Pt](R=4-[p-(N-butyl-N-phenyl)anilino]) segments.
