Metalloporphyrin-based porous organic polymers that behave as advanced biomimetic nanoreactors have drawn continuous attention for heterogeneous CO2 cycloaddition conversion in the past decades. However, use of homogeneous onium salts, usually acting nucleophilic cocatalysts, may increase cost product purification and cause additional environmental problems. In this contribution, a new aluminum porphyrin-based hyper-cross-linked polymer modified by imidazolium salts (denoted Im@Al-HCP) has been successfully constructed first time. The two-step process hyper-cross-linking reaction combined with postsynthetic modification endows catalyst large surface area (about 213 m2·g–1), good adsorption capacity (up to 1.45 mmol·g–1), highly dispersed cooperative active sites. Accordingly, bifunctional Im@Al-HCP exhibits an outstanding catalytic activity, recyclability, broad substrate generality without cocatalysts solvents under mild conditions. particular, high turnover frequency (TOF) value up 5000 h–1 can be acquired, which far exceeds most reported catalysts identical addition, as-made recycled at least six times obvious loss activity. This work not only bring some inspirations construction multifunctional but also provides great potential industrial applications cycloadditions.

Abstract Rising carbon dioxide (CO 2 ) levels in the atmosphere are recognized as a threat to atmospheric stability and life. Although this greenhouse gas is being produced on large scale, there solutions reduction indeed utilization of gas. Many these involve costly or unstable technologies, such air‐sensitive metal–organic frameworks (MOFs) for CO capture “non‐green” systems amine scrubbing. Conjugated microporous polymers (CMPs) represent simpler, cheaper, greener solution utilization. They often easy synthesize at scale (a one pot reaction many cases), chemically thermally stable (especially comparison with their MOF covalent organic framework (COF) counterparts, owing amorphous nature), and, result, cheap manufacture. Furthermore, surface areas, tunable porous chemical structures mean they reported highly efficient motifs. In addition, provide dual pathway utilize captured via conversion electrochemical into industrially valuable products. Recent studies show that all attractive properties can be realized metal‐free CMPs, presenting truly green option. The promising results two fields CMP applications reviewed explored here.
