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 have strong electron-donating ability and good redox properties.In this paper, a new type of conjugated-C ^ N ligand La and Lb were synthesized and their single crystal structures were confirmed by X-ray diffraction.A novel iridium complex [Ir (La) 2 (tpip)] based on these two ligands was further prepared (1, tpip is tetraphenyl Diphosphoimidazoles) and [Ir (Lb) 2 (tpip)] (2). The structures of all compounds were characterized by elemental analysis, infrared spectroscopy, nuclear magnetic resonance spectroscopy and mass spectrometry. Electrochemical properties were studied.
