A systematic expansion of the well-known non-interpenetrated and robust MOF-11 was accomplished through a rediscovery of the ligand tetrakis(4-carboxyphenyl)adamantane (L). The combination of a rigid tetrahedral L and copper(ii) paddle-wheel secondary building unit (SBU) resulted in a stable non-interpenetrated metal-organic framework, UOF-1 (UOF = University of Otago framework), with the predicted PtS topology. This MOF exhibits permanent porosity, as established by X-ray diffraction (XRD) and gas adsorption studies. This low-density open framework possesses one open-metal site per Cu(ii) cation which could be accessed by employing appropriate activation techniques such as the use of supercritical CO2 (s-CO2) or dry CH2Cl2. CO2 gas displayed higher affinity towards activated UOF-1 than CH4 and N2 gases at room temperature and low pressure. UOF-1 displayed excellent selectivity for CO2 over N2 of 52:1 at practical operating conditions of 15:85 CO2:N2 mixture at 273 K and 1 bar.

Reduction of anthropogenic CO2 emissions and CO2 separation from post-combustion flue gases are among the imperative issues in the spotlight at present. Hence, it is highly desirable to develop efficient adsorbents for mitigating climate change with possible energy savings. Here, we report the design of a facile one pot catalyst-free synthetic protocol for the generation of three different nitrogen rich nanoporous amide networks (NANs) based on tetraphenyladamantane. Besides the porous architecture, CO2 capturing potential and high thermal stability, these NANs possess notable CO2/N2 selectivity with reasonable retention while increasing the temperature from 273 K to 298 K. The quantum chemical calculations also suggest that CO2 interacts mainly in the region of polar amide groups (-CONH-) present in NANs and this interaction is much stronger than that with N2 thus leading to better selectivity and affirming them as promising contenders for efficient gas separation.
