New metal-organic frameworks (MOF) with lanthanum(III), cerium(III), neodymium(III), europium(III), gadolinium(III), dysprosium(III), and holmium(III)] and the ligand precursor 1,3,5-tris(4-carboxyphenyl)-2,4,6-trimethylbenzene (H3L) were synthesized under solvothermal conditions. Single crystal x-ray analysis confirmed the formation of three-dimensional frameworks of [LnL(H2O)2]n·xDMF·yH2O for Ln = La, Ce, and Nd. From the nitrogen sorption experiments, the compounds showed permanent porosity with Brunauer-Emmett-Teller (BET) surface areas of about 400 m2/g, and thermal stability up to 500 °C. Further investigations showed that these Ln-MOFs exhibit catalytic activity, paving the way for potential applications within the field of catalysis.

新型微孔稀土有机框架。 2-萘酚的合成、结构、发光、吸附和催化酰化


含有镧(III)、铈(III)、钕(III)、铕(III)、钆(III)、镝(III)和钬(III)的新型金属有机骨架(MOF)]和配体前体1在溶剂热条件下合成了,3,5-三(4-羧基苯基)-2,4,6-三甲苯(H3L)。单晶 X 射线分析证实了 Ln = La、Ce 和 Nd 时形成了 [LnL(H2O)2]n·xDMF·yH2O 三维骨架。从氮气吸附实验来看，这些化合物表现出永久的孔隙率，Brunauer-Emmett-Teller (BET) 表面积约为 400 m2/g，热稳定性高达 500 °C。进一步的研究表明这些Ln-MOF表现出催化活性，为催化领域的潜在应用铺平了道路。
