Creative assembly of bimetallic [ZnIITbIII(CO2)3(H2O)] clusters and the desigened bifunctional ligand of H6TDP engendered one highly robust anionic heterometallic framework {[(CH3)2NH2][ZnIITbIII(TDP)(H2O)]·3DMF·3H2O}n (NUC-7), which featured two types of nanochannels decorated with density open metal sites and free oxygen atoms on the wall. To the best our knowledge, NUC-7 represented one novel kind of heterometallic ZnII/LnIII-organic 3D honeycomb MOFs with exposed tetra-coordinated ZnII-metal sites as Lewis acid sites. Subsequent studies indicated that NUC-7 could highly adsorb CO2 and catalyze the cycloaddition of various epoxides into related carbonates with the help of cocatalyst TBAB under lukewarm conditions of 1 atm and 80 °C. Meanwhile, NUC-7 exhibited the effectively selective sensitivity for discriminating Fe3+ in aqueous solution by luminescence quenching. It could be inferred that the excellent characteristics including large void volume, high porosity, active open metal sites, and uncoordinated carboxylate oxygen atoms as Lewis acid and base sites rendered NUC-7 one ideal platform for gas reservoir, specific catalyst, and luminescence sensing.

纳米多孔Zn II / Tb III –用于CO 2转化的有机骨架
双金属[Zn II Tb III（CO 2）3（H 2 O）]团簇的创造性组装和H 6 TDP的去污双功能配体产生了一个高度坚固的阴离子杂金属骨架{[（（CH 3）2 NH 2 ] [Zn II Tb III（TDP）（H 2 O）]·3DMF·3H 2 O} n（NUC-7），具有两种类型的纳米通道，其壁上装饰有密集的开放金属位点和游离氧原子。据我们所知，NUC-7代表了一种新型的杂金属锌II / Ln III-有机3D蜂窝MOF，具有暴露的四配位Zn II-金属位点作为路易斯酸位点。随后的研究表明，在助剂TBAB的1atm和80°C温热条件下，NUC-7可以高度吸附CO 2并催化各种环氧化物环化成相关的碳酸酯。同时，NUC-7对通过发光猝灭来鉴别水溶液中的Fe 3+具有有效的选择性敏感性。可以推断出优异的特性，包括大的空隙体积，高孔隙率，活泼的开放金属位点以及未配位的羧酸根氧原子（路易斯酸和碱位点）NUC-7是用于储气库，特定催化剂和发光传感的理想平台。
