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}
n
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。
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}
n
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 (
3
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.
