A series of isoreticular metal–organicframeworks (MOFs; NENU‐511–NENU‐514), which all have high surface areas and strong adsorption capacities, have been successfully constructed by using mixed ligands. NENU‐513 has the highestbenzene capacity of 1687 mg g−1at 298 K, which ranks as the top MOF material among those reported up to now. This NENU series has been used for adsorptive desulfurization because
使用混合配体已成功构建了一系列具有高表面积和强吸附能力的等孔金属有机骨架(MOF;NENU‐511 – NENU‐514)。NENU‐513在298 K时的最高苯容量为1687 mg g -1,在迄今为止报道的那些中,它是MOF的首屈一指的材料。由于其永久的孔隙率,该NENU系列已被用于吸附脱硫。结果表明,与其他MOF材料(尤其是NENU-511)相比,该系列在去除有机硫化合物方面具有更高的吸附效率。,它在周围大气中具有最高的吸附效率。这项研究证明,具有较高表面积和官能团的目标MOF的设计和合成是提高苯存储能力和有机硫化合物吸附的有效方法。

Copper-Catalyzed Annulative Coupling of S,S-Disubstituted Enones with Diazo Compounds to Access Highly Functionalized Thiophene Derivatives
An efficient protocol toward fully substitutedthiophenes and thieno[2,3-b]thiophenes has been developed through CuCl2-catalyzed annulative coupling of S,S-disubstituted enones with diazo compounds under mild conditions. Tetrasubstituted thiophenes and thieno[2,3-b]thiophenes were efficiently accessed by variation of the feed ratio of the reactants in good to excellent yields, respectively. The synthetic
