摘　　要：以合成结构新颖的超分子聚合物为目标,基于双(2-羧乙基)异氰尿酸酯(简称BCLA)基础单元,在N,N-二甲基甲酰胺的溶剂体系下,水热95℃合成了无色透明块状的超分子聚合物[C9H3N3O7]n.通过X射线单晶衍射仪、FTIR、PXRD等对聚合物的结构进行了表征,结构分析表明:双(2-羧乙基)异氰尿酸酯聚合物官能团之间靠强烈的N-H…O和O-H…O氢键形成二维无限波浪状超分子结构,相邻的层状结构再由分子间弱作用力构筑成三维层状堆积结构;聚合物为单斜晶系,C2/c空间群.To synthesize novelly structure of supramolecular polymers.A colorless block crystal supramolecular polymers based on Bis（2-carboxyethyl）lsocyanurate units have been synthesized under the system of N,N-dimethylformanmide solvent in 95 ℃ hydrothermal conditions,named[C9H3N3O7]n,which containing different patterns of hydrogen bonds based on Bis（2-carboxyethyl）lsocyanurate units.And characterized by single crystal X-ray diffraction、FTIR and PXRD.Structural analysis shows that polymers′functional groups interacted with each other by the strong N-H…O and O-H…O hydrogen bonds into two-dimensional infinite wavy flat structure,which further extend into 3Dstacking structure via the weak forces from the adjacent layers.Polymer crystallizes in the monoclinic system,space group C2/c.
