“…Single-crystal X-ray diffraction data revealed that they also crystallize in tetragonal space group P 4 3 2 1 2 and are isostructural MOFs of NJTU-Bai79 with the metal ion changed. Notably, these MOFs are the first series of (3,6)-connected ant topological MOFs to be constructed from [Fe 2 M(μ 3 –OH)(COO) 6 (pyridyl) 2 ] clusters and the ligand containing both the pyridyl group and −COO groups. − …”

Solvothermal reactions of different trinuclear precursors and 5-(pyridin-4-yl)isophthalic acid (H 2 L) successfully led to four anionic ant topological MOFs as Fe 3−x M x (μ 3 −OH)(CH 3 COO) 2 (L) 2 •(DMA + )•DMF [M = Mn(II), Fe(II), Co(II), x = 0, 1, 2 and 3], namely, NJTU-Bai79 [NJTU-Bai = Nanjing Tech University Bai's group, Mn 3 (μ 3 −OH)], NJTU-Bai80 [Fe 2 Mn(μ 3 −OH)], NJTU-Bai81 [Fe 3 (μ 3 −OH)], and NJTU-Bai82 [Fe 2 Co(μ 3 −OH)], which possess the narrow pores (2.5−6.0 Å). NJTU-Bai80−82 is able to be tuned to the neutral derivatives [NJTU-Bai80−82(-ox), ox = oxidized] with M 2+ ions oxidized to M 3+ ones in the air and the OH − ions coordinated on M 3+ ions. Very interestingly, selective CO 2 /N 2 adsorptions of NJTU-Bai80−82(-ox) are significantly enhanced with the CO 2 adsorption uptakes more than about 6 times that of NJTU-Bai79. GCMC simulations further revealed that neutral NJTU-Bai80−82(-ox) supplies more open frameworks around the −CH 3 groups at separate spaces to the CO 2 gas molecules with relatively more pores available to them after the removal of counterions. For the first time, finely tuning metal ion valences of metal clusters of ionic MOFs and making them from electrostatic to neutral were adopted for greatly improving their CO 2 capture properties, and it would provide another promising strategy for the exploration of high-performance CO 2 capture materials.

Under hydrothermal condition, lactate derivative (R)‐4‐(1‐ carboxyethoxy)‐2‐methylbenzoic acid ((R)‐H2cma) as chiral synthon assembled with 4,4'‐di(1H‐imidazol‐1‐yl)‐1,1'‐biphenyl (4,4’‐dib) and Ni(II) ions to obtain complex {[Ni2((R)‐cma)2(4,4’‐dib)2(H2O)]·2H2O}n (HU20‐R). In complex HU20‐R, carboxyl group from lactate unit of (R)‐cma2‐ anion and coordinating H2O molecule adopt a μ2‐coordination mode to obtain dinuclear [Ni2(CO2)2(H2O)]2+ cluster. (R)‐cma2‐ anions and Ni(II) ions build single left‐handed (R)‐cma‐Ni‐chain, while 4,4’‐dib ligands are bridged by different Ni(II) centers to form double left‐handed 4,4’‐dib‐Ni‐chain. These helical secondary structures are further connected together to result in an 8‐connected 3D framework. PXRD tests indicated that complex HU20‐R has well hydro‐stability. UV‐vis absorption experiment confirmed that HU20‐R is a semi‐conducting material with strong absorption capacity for ultraviolet‐visible (UV‐vis) light. Additionally, electrochemical experiment revealed that HU20‐R has low impedance and high charge transport capacity. Further test results confirm that HU20‐R has noticeable photo‐catalytic effect in photodegradation of Rhodamine B (RhB) and antiferromagnetic property.
