摘要

在固体状态下保持其多孔功能的介孔金属有机笼或多面体（moc或MOPs）的合成仍然具有挑战性，因为它们在溶解时容易崩溃。在此，我们报告了使用等孔膨胀法在介孔体系内合成两个永久多孔Rh（II）基八面体MOPs。我们的介孔MOPs具有高达12.5 nm³的内腔，可以承受活化过程，使其成为气体和水的固态吸附剂。特别是，更大的介孔MOP，命名为BCN-17，可捕获0.47 gmp·ggmp -1，并表现出具有介孔材料特征的s形吸水等温线和滞后环。

Isoreticular Synthesis of Mesoporous Metal-Organic Polyhedra with Permanent Porosity to Gas and Water.

Synthesis of mesoporous metal-organic cages or polyhedra (MOCs or MOPs) that retain their porous functionality in the solid state remains challenging, given their tendency to collapse upon desolvation. Herein, we report the use of the isoreticular expansion approach to synthesize two permanently porous Rh(II)-based octahedral MOPs within the mesoporous regime. Our mesoporous MOPs, featuring internal cavities of up to 12.5 nm³, withstand the activation process, enabling their use as solid-state adsorbents for gases and water. In particular, the larger mesoporous MOP, named BCN-17, captures up to 0.47 gwater·gMOP-1 and exhibits an S-shaped water-sorption isotherm with a hysteresis loop, characteristic of mesoporous materials.
