“…Here, the solubility of non-networking POPs offers the advantages of NPs synthesis via thermal decomposition of metal precursors in the polymer solution over the wet impregnation method since more parameters could be finely tuned during the synthesis to afford the well-defined, uniform NPs with predicted size and morphology. The resulting nanocomposites are now of particular interest for catalysis [11,12,[23][24][25]. The presence of microand mesopores restricts the growth of NPs within the polymer matrix while allowing the easy access and diffusion of substrate molecules in the resulting catalytic composites.…”

“…The ease of functionalization, unique topologies, extraordinary stability, and solution processability of non-networking POPs boost the research interest in expanding the chemistry underlying the non-networking POPs synthesis. Along with spirobisindane and polybenzodioxin [20,26], triptecene [27][28][29], and porphirine-based [25] monomers that are widely established structural units in the synthesis of soluble microporous polymers so-called polymers of intrinsic microporosity (PIMs), many other building blocks, such as phenantroline [30], benzylamine [31], bisphosphine [32], and phtalocyanine [33], have been utilized to create microporosity in polymers. Phenylenes of different structures are another class of compounds capable of forming micropores.…”

Development of new microporous organic polymers attracts significant attention due to a wide scope of promising applications. In addition, the synthesis of soluble, non-crosslinking polymers of high surface area and uniform microporosity is very challenging, and the methods for soluble microporous polymers formation are rather limited. In this work, we report a new approach to construct porous polyphenylenes which employs the Diels–Alder polycondensation of multifunctional ethynyl-containing monomers of different spatial architecture with bis(cyclopentadienone)s. The resulting polymers were soluble in common organic solvents, and their structure and properties were assessed by NMR, TGA, DSC, and SEC studies. The polymers demonstrated a specific surface area up to 751 m2·g−1 and ultramicroporous (pore size ≤ 0.6 nm) structure. N2 and CO2 adsorption–desorption data revealed that porosity parameters, e.g., specific surface area and pore sizes, can be tuned selectively by varying the type of monomers and reaction conditions.

Post‐synthetic Modification of DUT‐5‐based Metal Organic Frameworks for the Generation of Single‐site Catalysts and their Application in Selective Epoxidation Reactions

New single‐site catalysts based on mixed‐linker metal‐organic frameworks with DUT‐5 structure, which contain immobilized Co2+, Mn2+ and Mn3+ complexes, have successfully been synthesized via post‐synthetic modification. 2,2’‐Bipyridine‐5,5’‐dicarboxylate linkers were directly metalated, while 2‐amino‐4,4’‐biphenyldicarboxylate linkers were post‐synthetically modified by their conversion to Schiff‐base ligands and a subsequent immobilization of the metal complexes. The resulting materials were used as catalysts in the selective epoxidation of trans‐stilbene and the activities and selectivities of the different catalysts were compared. The influence of various reaction parameters on conversion, yield and selectivity were investigated. Very low catalyst amounts of 0.02 mol % were sufficient to obtain a high conversion of trans‐stilbene using molecular oxygen from air as the oxidant. For cobalt‐containing MOF catalysts, conversions up to 90 % were observed and, thus, they were more active than their manganese‐containing counterparts. Recycling experiments and hot filtration tests proved that the reactions were mainly catalyzed via heterogeneous pathways.
