摘　　要：以具有高摩尔吸光系数、高荧光量子产率和良好平面性的六元环等优点的1,3-二酮二氟化硼类化合物为研究对象,设计合成一种不对称的1,3-二酮二氟化硼化合物,并用紫外可见吸收光谱和荧光发射光谱检测其在溶液中的变化,用原子力显微镜观察其形貌,测量其组装体的大小.实验结果表明,1,3-二酮二氟化硼在水比例增加的情况下发生了明显的组装行为,其组装体呈规则、有序的带状结构.The 1,3-dione boron difluoride compounds were used as the research object based on the advantages of high molar absorption coefficient,high fluorescence quantum yield,good planar six-member ring and so on.The author designed and synthesized an asymmetric 1,3-dione boron difluoride compound,detected its changes in solution by using ultraviolet visible absorption spectrum and fluorescence emission spectrum,and observed its morphology by using atomic force microscopy and measured the size of its assembly.The experimental results show that there is a significant assembly behavior of 1,3-dione boron difluoride with an increase in water ratio,and its assembly body exhibits a regular and ordered banded structure.
