摘要

Six new metal-organic frameworks, namely, {[Co(btmb)(HBTC)]?2H _2O}_n (1), {[Co_3(btmb)_3(BTC) _2(H_2O)_2]?6H_2O}_n (2), {[Co_3(btmb)_3(BTC)_2(H_2O) _4]?2H_2O}_n (3), {[Ni_3(btmb) _3(BTC)_2(H_2O)_4]?2H _2O}_n (4), [Cu(btmb)(HBTC)]_n (5), and [Cu(btmb)(NDC)]_n (6) (H_3BTC = 1,3,5-benzenetricarboxylic acid, H_2NDC = 1,2-benzenedicarboxylic acid, and btmb = 4,4′-bis(1,2,4-triazol-1-ylmethyl)biphenyl), have been synthesized under hydrothermal conditions. The structure of 1 is a 6-connected self-penetrating three-dimensional (3D) framework with 4~4?6~(10)?8 topology. Complex 2 exhibits a trinodal (3,4)-connected topology with a Schl?fli symbol of (6~2?8~4)(6~4? 8~2)(6~3). Both complexes 3 and 4 possess 3D pillar-layered structures with a Schl?fli symbol of (6~2?8?10 ~3)(6~4?8?10)(6?10~2). Complex 5 is also a 3D polymer with a pillar-layered framework, which can be simplified as the (6~3)(6~9?8) topology. Complex 6 shows a 4-connected 3D framework with a Schl?fli notation of (6~5?8) _2. Furthermore, complexes 1-6 as heterogeneous catalysts were studied in the green catalysis process of the oxidative coupling of 2,6-dimethylphenol (DMP) to poly(1,4-phenylene ether) (PPE) and diphenoquinone (DPQ). The results show that these complexes exhibit different catalytic activities; both the Cu complexes are catalytically active by showing high conversion of DMP and high selectivity of PPE, and they exhibit great potential as recyclable catalysts.
