A stepwise ligand exchange strategy is utilized to prepare a series of isoreticular bio-MOF-100 analogues. Specifically, in situ ligand exchange with progressively longer dicarboxylate linkers is performed on single crystalline starting materials to synthesize products with progressively larger mesoporous cavities. The new members of this series of materials, bio-MOFs 101-103, each exhibit permanent mesoporosity and pore sizes ranging from ~2.1-2.9 nm and surface areas ranging from 2704 to 4410 m(2)/g. The pore volume for bio-MOF 101 is 2.83 cc/g. Bio-MOF-102 and 103 have pore volumes of 4.36 and 4.13 cc/g, respectively. Collectively, these data establish this unique family of MOFs as one of the most porous reported to date.
采用逐步配体交换策略来制备一系列同构的生物 MOF-100 类似物。具体而言，在单晶起始材料上进行原位配体交换，用逐渐更长的二羧酸配体来合成具有逐渐更大介孔腔的产物。该材料系列的新成员，生物 MOFs 101-103，每个都表现出永久介孔性和孔径范围为~2.1-2.9nm 以及比表面积范围为 2704 至 4410m²/g。生物 MOF 101 的孔体积为 2.83cc/g。生物 MOF-102 和 103 的孔体积分别为 4.36 和 4.13cc/g。总的来说，这些数据表明这一独特的 MOF 家族是迄今为止报道的最具多孔性的 MOF 之一。
