    Polyketones with a Well-Defined 1,3,5-Triphenyloylbenzene Subunit via

    Cyclotrimerization of Enaminones for Gas Separations

    ACS Appl. Polym. Mater. 2025, 7, 5616?5623.

    Porous

    organic polymers (POPs) functionalized with carbonyl groups have

    attracted much attention not only due to the inherent properties of

    polyketones but also for their rich postfunctionalizations. However, the

    synthesis of porous polyketone is very limited, mainly through

    AlCl3-mediated Friedel?Crafts acylation polymerization of aromatic

    hydrocarbons, which faced issues such as undefined polyacylation

    products, reactivity decreasing with polymerization going on, and the

    residual AlCl3 in the polymers. In order to have a well-defined

    structure of porous polyketones to advance the research of porous

    materials, this Article developed cyclotrimerization polymerization of

    tris-enaminones to access a class of porous polyketones based on

    1,3,5-triphenylacetylbenzene structural units named BIT-POP-80 ~

    BIT-POP-82, with a BET surface area up to 580 m2 g?1. Considering the

    affinity of the carbonyl group to CO2, the as-synthesized porous

    polyketones were doped into the polysulfone matrix as a porous filler to

    make mixed matrix membranes (MMMs). It is found that the MMMs

    effectively improved the permeability of CO2 by 150% as well as the gas

    pair selectivity of CO2/CH4. The cyclotrimerization polymerization of

    enaminones reported in this paper provided a powerful approach to

    functionalized porous polymer materials with well-defined structure.
