“…In 2020, Zou et al described a tetraphenylporphyrin knitting polymer following method-1 as a support for Pd NPs. 100 By the postfunctionalization strategy, PdCl 2 was coordinated to the porphyrin ring and subsequently reduced with NaBH 4 , resulting in the catalysts denoted as HUST-1-Pd (Figure 15e). The same techniques previously commented were employed to confirm the Pd(0) oxidation state, and the particle size was found to be about 5.5 nm by TEM experiments.…”

In 2011, a new type of hyper-cross-linked polymers (HCPs) arose, known as knitting aromatic polymers (KAPs), characterized by their extraordinary chemical and thermal stability, by their porosity properties, and above all, for the simplicity of their synthesis based on the union of aromatic monomers, without any previous functionalization. The next logical step was the incorporation of metals within these networks, as support for different soluble molecular catalysts or metal nanoparticles (NPs). Thus, the number of metal-containing KAPs has been gradually growing in the past decade, and we have considered that now, in the 10th anniversary of the first KAPs reported, a review of all the metal-containing KAPs and their application as heterogeneous metal catalysts is mandatory. In this review, the most relevant characteristics of all KAPs that contain metals are summarized, divided into two large groups, either as metal complexes or as metal NPs, and classified according to the type of metal incorporated. Finally, the catalytic activities were compared based on the metal employed in each studied reaction, and the future goals of these types of materials are commented on.

The resulting networks of H-HOPS showed superb thermal stability in nitrogen atmosphere, as revealed by TGA ( Figure S2).…”

A novel hybrid porous polymer with hollow vesicle structure has been synthesized via Friedel-Crafts alkylation reaction and solvent-induced method. The resulting two-dimensional networks are hierarchical porous materials with high Brunauer-Emmett-Teller (BET) surface area of 1582 m 2 g À 1. The vesicle structure directly influenced the activity and shaping the performance of the catalyst. The kinetic study reveals the special vesicle structure can enrich the substrates in a limit scope and increase the reaction rate. It has been demonstrated that the framework and morphology play a major role on the catalysts' excellent performance in Suzuki-Miyaura cross-coupling reaction of aryl chlorides. These findings help elucidate the mode action of the vesicle structure in the unrevealed Suzuki reaction mechanism of supports and the potential development of new morphology control catalysts.

“…Fortunately, hot filtration test validated that there was an insignificant leaching of the Pd species. PdNP–HCPs can also be prepared by Friedel–Crafts alkylation reaction using 4‐tritylaniline, [ 60 ] substituted 1,2,3‐triazoles, [ 61 ] and 5‐,10‐, 15‐, and 20‐tetraphenylporphyrin [ 62 ] as the monomer and FDA or dichloromethane as the cross‐linker, respectively. And the resulting materials were proven to be a suitable catalyst for promoting Suzuki coupling reaction, and hydrogenation of ammonia borane, nitro compounds, or α,β‐unsaturated aldehydes.…”

Direct knitting of nucleophilic arene monomers in the presence of electrophilic cross‐linker, like formaldehyde dimethyl acetal, is proven to be a cost‐effective and versatile method for the synthesis of porous organic polymers. The resulting hypercrosslinked polymers (HCPs) are featured by hierarchical porous structure, high surface area, and pore volume. Coordinating functional groups can be easily installed with this method into the rigid aryl network. Direct knitting to HCPs has therefore been widely used in preparing heterogeneous solid catalysts. Wise selection of monomers with rational design of 3D structure and the synergy between the HCP support and the catalytically active species often lead to high efficiency of tailor‐made catalysts without sophisticated operations. On account of all these excellent properties, enthusiasm of researchers to use HCPs in catalysis is increasing rapidly. This review documents the necessity, feasibility, and the great contributions of using HCPs as invaluable tools for catalysis research, and summarizes state of the art of this chemistry. Similar type catalysts obtained by one‐step Scholl reaction are also included in this review.
