A 3D supermolecular structure Co(L) (2,2'-bipy)(HO) 1) (HL = 4,4',4″-nitrilotribenzoic acid) has been constructed based on HL, and 2,2'-bipy ligands under solvothermal conditions. Compound can be described as a (3, 6)-connected kgd topology with a Schläfli symbol (4)(4.6.8) formed by [Co(CO)] secondary building units. The adsorption properties of the activated sample 1a has been studied; the result shows that 1a has a high adsorption ability: the CO uptakes were 74 cm·g at 273 K, 50 cm·g at 298 K, the isosteric heat of adsorption (Q) is 25.5 kJ mol at zero loading, and the N adsorption at 77 K, 1 bar is 307 cm g. Magnetic measurements showed the existence of an antiferromagnetic exchange interaction in compound , besides compound exhibits effective luminescent performance for Fe/Cr and TNP.
在溶剂热条件下，基于4,4',4″-次氮基三苯甲酸（HL）和2,2'-联吡啶配体构建了一种三维超分子结构Co(L)(2,2'-bipy)(H₂O)₁。化合物可描述为具有(4)(4.6.8)施莱夫利符号的(3,6)-连接kgd拓扑结构，由[Co(CO)]次级构筑单元形成。研究了活化样品1a的吸附性能；结果表明1a具有高吸附能力：在273 K时CO吸附量为74 cm³·g⁻¹，在298 K时为50 cm³·g⁻¹，零负载下的等量吸附热(Qst)为25.5 kJ mol⁻¹，在77 K、1 bar下N₂吸附量为307 cm³ g⁻¹。磁性测量表明化合物中存在反铁磁交换相互作用，此外化合物对Fe³⁺/Cr₂O₇²⁻和TNP表现出有效的发光性能。
