The targeted synthesis of a novel ionic porous organic polymer (iPOP) was reported. The compound (denoted as QUST-iPOP-1) was built up through a quaternization reaction of tris(4-imidazolylphenyl)amine and cyanuric chloride, and then benzyl bromide was added to complete the quaternization of the total imidazolyl units. It featured a special exchangeable Cl − /Br −rich structure with high permanent porosity and wide pore size distribution, enabling it to rapidly and effectively remove environmentally toxic oxo-anions including Cr 2 O 7 2− , MnO 4 − , and ReO 4 − and anionic organic dyes with different sizes including methyl blue, Congo red, and methyl orange from water. Notably, QUST-iPOP-1 showed ultra-high capacity values for radioactive TcO 4 − surrogate anions (MnO 4 − and ReO 4 − ), Cr 2 O 7 2− , methyl blue, and Congo red, and these were comparable to some reported compounds of exhaustive research. Furthermore, the relative removal rate was high even when other concurrent anions existed.

A novel tri-functional MOF catalyst was achieved by PSM method. Because of the synergistic effect of Lewis acid, Brønsted acid and Br− anion, MIL-IMAc-Br− displayed an efficient catalytic performance for CO2 conversion.

A new strategy toward constructing bifunctional catalyst for CO2 cycloaddition has been developed based on post-synthetic modification of CUS-based metal-organic frameworks (MOFs) with ionic porous organic frameworks (POFs) to form...
