摘 要：采用2-吡咯甲醛与2-氨甲基吡啶反应，制备了三齿席夫碱配体HL1 。在表面活性剂聚乙烯吡咯烷酮存在时，在甲醇溶液中，由配体HL1与三乙基胺、四氟合硼酸铜(Ⅱ)、碘及KBr作用，得到铜(II)配合物 [Cu2(L3)2(-Br)2]微/纳米结构材料。对配体进行了红外光谱、核磁共振氢谱、质谱表征，对配合物微/纳米材料的结构进行了红外光谱、XRD、单晶X-射线衍射表征，对微/纳米结构材料的形貌用扫描电子显微镜（SEM）进行了表征。XRD分析表明加了表面活性剂制备得到的配合物微/纳米材料与不加表面活性剂得到的是同一种物质，且结构相同。还研究了聚乙烯吡咯烷酮的用量和反应时间对配合物微/纳米材料形貌和尺寸的影响。67109

Abstract：Tridentate Schiff Ligands HL1 was obtained by reacting pyrrole-2-carboxaldehyde with 2-(2-aminoethyl)pyridine. In the presence of polyvinylpyrrolidone as a surfactant, copper (II) complex micro/nano structural material [Cu2(L3)2(-Brl)2] was obtained by mixing ligand HL1, copper(II) tetrafluoroborate hydrate, iodine and potassium bromide, in methanol, using triethyleneamine as a base. Ligand HL1 was characterised by IR, 1H NMR and ESI-MS. Structure of the micro/nano material was analysed by IR, powder X-ray deffraction (XRD) and single crystal X-ray deffraction determination. Morphology of the micro/nano material was inspected using a scanning electron microscope. Powder X-ray analysis shows that structure of the micro/nano material prepared by the procedure with polyvinylpyrrolidone as a surfactant is the same as that obtained from the procedure without the surfactant polyvinylpyrrolidone. Influences of the amount of surfactant and reaction time on the morphology of the micro/nano material were investigated.

Keywords：Schiff base, polyvinylpyrrolidone, copper(II) complexes, nano-sized materials
