Abstract

The stability and functionality of metal-organic frameworks (MOFs) are particularly important in considering their potential and/or practical use. Herein we report two novel aldehyde functional group-containing MOFs [Zn(L)(BDC)]·2DMF·MeOH·HO (1) and [Co(L)(BDC)]·2DMF·2MeOH·HO (2) (DMF = N,N-dimethylformamide, MeOH = methanol) achieved by reactions of mixed organic ligands of 2,4-bis[(pyridin-4-yl)methoxy]benzaldehyde (L) and 1,4-benzenedicarboxylic acid (HBDC) with the corresponding metal salts under solvothermal conditions. Both 1 and 2 are 2-fold interpenetrated three-dimensional (3D) frameworks. Particularly, 1 exhibits excellent water and wide-range pH stability, and a large Q value for carbon dioxide (CO) adsorption. Furthermore, photoluminescence (PL) studies indicate that 1 could be considered as a potential luminescent probe for detection of nitroaromatics.

摘要

金属-有机骨架（MOFs）的稳定性和功能性在考虑其潜在和/或实际用途时尤为重要。在此，我们报告了两种新型醛官能团含 MOFs [Zn(L)(BDC)]·2DMF·MeOH·HO（1）和[Co(L)(BDC)]·2DMF·2MeOH·HO（2）（DMF = N，N-二甲基甲酰胺，MeOH =甲醇），通过混合有机配体 2,4-双[(吡啶-4-基)甲氧基]苯甲醛（L）和 1,4-苯二甲酸（HBDC）与相应的金属盐在溶剂热条件下反应得到。1 和 2 都是 2 倍穿插的三维（3D）骨架。特别是 1 表现出优异的水和宽 pH 稳定性，以及对二氧化碳（CO）吸附的大 Q 值。此外，光致发光（PL）研究表明，1 可以被认为是检测硝基芳烃的潜在发光探针。
