In this study, a commercially available homogeneous pincer-type complex, Ru-Macho, was directly heterogenized via the Lewis acid-catalyzed Friedel–Crafts reaction using dichloromethane as the cross-linker to obtain a heterogeneous, pincer-type Ru porous organometallic polymer (Ru-Macho-POMP) with a high surface area. Notably, Ru-Macho-POMP was demonstrated to be an efficient heterogeneous catalyst for the chemoselective hydrogenation of α,β-unsaturated carbonyl compounds to their corresponding allylic alcohols using cinnamaldehyde as a model compound. The Ru-Macho-POMP catalyst showed a high turnover frequency (TOF = 920 h–1) and a high turnover number (TON = 2750), with high chemoselectivity (99%) and recyclability during the selective hydrogenation of α,β-unsaturated carbonyl compounds.

The use of zinc glutarate (ZnGA) as a heterogeneous catalyst for the copolymerization of epichlorohydrin, an epoxide with an electron-withdrawing substituent, and CO2 is reported. This catalyst shows the highest selectivity (98%) for polycarbonate over the cyclic carbonate in epichlorohydrin/CO2 copolymerization under mild conditions. The (epichlorohydrin-co-CO2 ) polymer exhibits a high glass transition temperature (Tg ), 44 °C, which is the maximum Tg value obtained for the (epichlorohydrin-co-CO2 ) polymer to date.

Human lysophosphatidic acid receptor 1 (LPA1 ) is a G‐protein coupled receptor that mediates various biological functions such as proliferation, platelet aggregation, smooth muscle contraction, and tumor cell invasion. For dissection of the molecular function of LPA1 , a recombinant LPA1 was overexpressed in Escherichia coli membrane fractions and purified to homogeneity by single affinity chromatography. The purified LPA1 was stabilized with an amphiphilic polymer that was synthesized by the coupling of octylamine, glucosamine, and diethylaminoproylamine at the carboxylic groups of poly‐γ‐glutamic acid. The complex of purified LPA1 and amphiphilic polymer showed a monodisperse oligomer and specific binding to LPA with apparent Ki values of 30 μM. Compared with the Gs protein, it also showed selective binding to the alpha subunit of the Gi protein. These results indicate that recombinant LPA1 in an amphiphilic polymer complex has an active conformation for interaction with ligands and G‐proteins.

In the context of CO2 utilization, a number of CO2 conversion methods have been identified in laboratory‐scale research; however, only a very few transformations have been successfully scaled up and implemented industrially. The main bottleneck in realizing industrial application of these CO2 conversions is the lack of industrially viable catalytic systems and the need for practically implementable process developments. In this study, a simple, highly efficient and recyclable ruthenium‐grafted bisphosphine‐based porous organic polymer (Ru@PP‐POP) catalyst has been developed for the hydrogenation of CO2 to N,N‐dimethylformamide, which affords a highest ever turnover number of 160 000 and an initial turnover frequency of 29 000 h−1 in a batch process. The catalyst is successfully applied in a trickle‐bed reactor and utilized in an industrially feasible continuous‐flow process with an excellent durability and productivity of 915 mmol h−1 gRu−1.
