| الوصف: | The prevalence of the condensed phase, interpenetration, and fragility of ruesoporous coordination polymers (meso-PCPs) featuring dense open metal sites (OMSs) place strict limitations en their preparation, as revealed by experimental and `theoretical reticular chemistry investigations. Herein, we propose a rational design of stabilized high-porosity meso-PCPs, employing a `low-symmetry ligand in combination with the shortest linker, formic acid. The resulting dimeric dusters (PCP-31 and PCP-32) exhibit high surface areas, ultrahigh porosities, and high OMS derisities (3.76 and 3.29 nmol g(-1) respectively), enabling highly selective- and effective separation of C2H2 from C2H2/CO2 mixtures at 298 K, as verified by binding energy (BE) and electrostatic potentials (ESP) calculations. |
