摘要

利用两种半柔性的π-不饱和双吡啶端基配体与CuI配位，分别通过结构转化法和原位组装法，得到两种具有{[CuIL]·solvents}

结构通式的二维和三维碘化亚铜配位聚合物，分别命名为Cu-3和Cu-4。利用X射线单晶衍射、X射线粉末衍射和元素分析等表征方法确定了Cu-3和Cu-4的结构信息。研究这两种配位聚合物的光物理性能发现，用紫外光激发时，Cu-3和Cu-4均表现出单一发射峰，最大波长分别为513 nm的蓝绿光和555 nm的黄色光，归属于卤素到配体的电荷转移（

XLCT）。同时，这两种配位聚合物均表现出双光子激发发光性质，有望应用于生物成像领域。

Abstract

Through structural transition method or

in-situ

assembly method

two semi-flexible π-conjugated unsaturated bipodal-ligands were coordinated with CuI to obtain 2-D or 3-D cuprous iodide coordination polymerizations with the general structure of {[CuIL]·solvents}

namely Cu-3 and Cu-4

respectively. The structural information of Cu-3 and Cu-4 was determined by X-ray single crystal diffraction

powder X-ray diffraction and elemental analysis. Studying the photophysical properties of these two coordination polymers revealed that when excited by ultraviolet light

Cu-3 and Cu-4 showed a single emission peak with blue-green light at 513 nm and yellow light at 555 nm

respectively

which were attributed to halogen to ligand charge transfer (

XLCT) state. At the same time

these two coordination polymers both exhibit two-photon excited luminescence properties

and are expected to be used in the field of biological imaging.
