Abstract

Two metal-organic frameworks (MOFs), [Zn(BIPA)(tfbdc)]n (1) and {[Cd(BIPA)(tfbdc)(H2O)]·DMF}n (2), were hydrothermally synthesized using the self-assembly of the "V-shape" BIPA ligand (bis(4-(1H-imidazol-1-yl)phenyl)amine) and the H2tfbdc ligand (2,3,5,6-tetrafluorobenzene-1,4-dicarboxylic acid) with Zn/Cd metal salts. 1 is a 2D hcb framework and 2 is a 2D sql network. Their applications in detecting metal and inorganic ions were also explored. The results indicate that 1 exhibits dual-responsive photoluminescence sensing for Fe3+ and Cr2O72- ions while 2 can detect Hg2+ and Cr2O72- ions.

摘要

两个金属有机骨架（MOFs），[Zn（BIPA）（tfbdc）]n（1）和{[Cd（BIPA）（tfbdc）（H2O）]·DMF}n（2），是通过“V 形”BIPA 配体（双（4-（1H-咪唑-1-基）苯基）胺）和 H2tfbdc 配体（2,3,5,6-四氟苯-1,4-二羧酸）与 Zn/Cd 金属盐的自组装水热合成的。1 是二维 hcb 骨架，2 是二维 sql 网络。还探索了它们在检测金属和无机离子方面的应用。结果表明，1 对 Fe3+和 Cr2O72-离子表现出双重响应光致发光传感，而 2 可以检测 Hg2+和 Cr2O72-离子。
