含共轭四硫富瓦烯C^N配体铱配合物的合成与性质

Synthesis and properties of new Iridium complexes based on π conjugated ligands with tetrathiafulvalene

四硫富瓦烯(TTF)及其衍生物具有强的给电子能力以及良好的氧化还原性质.本文将吡啶基团通过苯基与TTF骨架连接,成功合成了新型?共轭C^N配体La和Lb,并利用X射线衍射谱确定了它们的单晶结构.进一步制备了基于这2个配体的新颖铱配合物[Ir(La)2(tpip)](1,tpip为四苯基二亚磷酸酰亚胺)和[Ir(Lb)2(tpip)](2).利用元素分析、红外光谱、核磁共振光谱、质谱等手段对所有化合物的结构进行了表征,并对其光化学和电化学性质进行了研究.

Tetrathiafulvalene （TTF） and its derivatives are unique π-electron donor and they show rich redox properties. In this paper, two new conjugated C∧N ligands based on TTF （La and Lb） have been synthesized and their structures are determined by X-ray crystallography. Iridium complexes, [Ir（La）2（tpip）] （1, tpip=tetraphenylimido-diphosphinate） and [Ir（Lb）2（tpip）] （2）, based on the two ligands have been synthesized. All new compounds are characterized by elemental analysis, IR, 1H NMR and MALDI-TOF-MS methods. The electrochemical and spectroscopic properties including UV-Vis absorption spectra and photoluminescence for 1 and 2 are studied.
