A luminescent triarylboron ligand functionalized with three carboxylic groups has been synthesized and fully characterized. Its use in boron-containing metal-organic frameworks (B-MOFs) has been demonstrated by the synthesis and isolation of a (ZnB)-B-II-MOF compound (B-MOF-1). The crystals of B-MOF-1 belong to the cubic space group F432 with 8-fold interpenetrated networks and similar to 21% void space. B-MOF-1 exhibits blue fluorescence and is capable of modest gas sorption of N-2, argon, and CO2.

Homochiral octupolarmetal−organoboronframeworks with the general formula [M2L(OH)(MeOH)]·3H2O [M = Co (1), Mn (2), Ni (3), Cu (4), Zn (5), Cd (6)] have been constructed from racemic C3-symmetric tris(4-benzoic acid)tridurylborane and the divalent metal ions. Compounds 1−6 are isostructural and crystallize in the chiral cubic space group F432, and they adopt an eightfold-interpenetrating (10,3)-a

construction of frustrated Lewis pairs (FLPs) in a metal–organicframework (MOF), where both Lewisacid (LA) and Lewis base (LB) are fixed to the backbone. The anchoring of a tritopic organoboron linker as LA and a monotopic linker as LB to separate metal oxide clusters in a tetrahedron geometry allows for the precise control of distance between them. As the type of monotopic LB linker varies, pyridine, phenol
我们报告了金属有机骨架(MOF)中受挫路易斯对(FLP)的构建,其中路易斯酸(LA)和路易斯碱(LB)都固定在主链上。锚定三位有机硼连接体 LA 和单位连接体 LB 以分离四面体几何形状中的金属氧化物簇,从而可以精确控制它们之间的距离。由于单位 LB 连接体的类型不同(吡啶、苯酚、苯胺和苯甲醇),构建了一系列 11 个 FLP,分别给出 7.1、5.5、5.4 和 4.8 Å 的固定距离,由11 B– 1 H 揭示固态核磁共振波谱。将 LA 和 LB 保持固定距离使得可以通过改变单位 LB 连接体中的官能团来研究静电效应,而 LA 对应物不受影响。这种方法为 FLP 诱导的催化活性位点提供了新的化学环境。
