摘要

原位二硫键形成提供了一种新的柔性二羧酸配体3,3 ' -二硫代双苯甲酸(3,3 ' - h2dtba)，该配体与Co(ii)离子在水热条件下组装，生成了一种新的金属有机骨架(MOF)，即[Co(3,3 ' -DTBA) 2 (h2o) 2] n(1)。该化合物由层状结构组装而成，具有层间弱相互作用，可以通过相对滑动减少孔隙堵塞。光催化实验结果表明，MOF 1是一种良好的半导体材料，在紫外光照射下可作为降解亚甲基蓝的光催化剂。循环实验证明其具有良好的稳定性和持久的光催化性能，具有潜在的应用价值。

In situ ligand synthesis affording a new Co(ii) MOF for photocatalytic application

Abstract In situ disulfide bond formation affords a new flexible dicarboxylic acid ligand of 3,3′-dithiobisbenzoic acid (3,3′-H 2 DTBA), which assembled with Co( ii ) ions under hydrothermal conditions, generating a novel metal–organic framework (MOF), namely, [Co(3,3′-DTBA) 2 (H 2 O) 2 ] n ( 1 ). This compound is assembled from layered structures, featuring weak interlayer interactions that can reduce pore blockage through relative sliding. The results of photocatalytic experiment indicate that MOF 1 is a good semiconducting material and it can function as photocatalyst for degrading methylene blue under the ultraviolet light irradiation. Cyclic experiments demonstrated its good stability and long-lasting photocatalytic performance, indicating its potential application value.

期刊介绍： Science and Engineering of Composite Materials is a quarterly publication which provides a forum for discussion of all aspects related to the structure and performance under simulated and actual service conditions of composites. The publication covers a variety of subjects, such as macro and micro and nano structure of materials, their mechanics and nanomechanics, the interphase, physical and chemical aging, fatigue, environmental interactions, and process modeling. The interdisciplinary character of the subject as well as the possible development and use of composites for novel and specific applications receives special attention.
