“…It is clear that the absorbed volume of nitrogen increases dramatically at low relative pressure and slowly at high relative pressure. Moreover, a slight hysteresis can be observed in the desorption isotherm, indicating the presence of micropores and mesopores in Fc‐HPP . The surface area of Fc‐HPP was determined by the specific Brunauer–Emmett–Teller surface area ( S BET ) method.…”

A novel ferrocene-linked organic-inorganic hybrid porous polymer has been successfully prepared by Friedel-Crafts reaction of octavinylsilsesquioxane and ferrocene. The relationship of structure/property was investigated by FTIR, NMR, XRD, Brunauer-Emmett-Teller (BET) etc. The obtained porous polymer exhibited a high surface area of 1015 m g and a hierarchical pore structure. It could be applied to wastewater treatment with the absorption capacity of up to 1683 mg g for Congo red (CR), 1083 mg g for crystal violet (CV), 1003 mg g for rhodamine B (RB), 441 mg g for methylene blue (MB), 191 mg g for Hg , and 328 mg g for Pb . Remarkably, it could be easily regenerated and the removal efficiency remains almost constant even after six cycles.

“…23 The synthesis of new azobenzene-doped hybrid porous polymers was thus possible. 24 Scheme 5 Pd-catalyzed Heck reaction of 4-bromoazobenzene 23 Poly(phenylenevinylene)-based conjugated polymers with azobenzene derivatives incorporated directly in the conjugative building units were prepared in quantitative yield and with a high molecular weight (M n >10000) by coupling polymerization of divinylbenzenes with 4,4′-di-haloazobenzenes. 25 The Heck reaction of nipecotic acid (piperidine-3-carboxylic acid) derivatives with azobenzene triflates and iodides yielded vinyl ethers in good yields.…”

Azobenzenes are among the most extensively used molecular switches for many different applications. The need to tailor them to the required task often requires further functionalization. Cross-coupling reactions are ideally suited for late-stage modifications. This review provides an overview of recent developments in the modification of azobenzene and its derivatives by cross-coupling reactions.1 Introduction2 Azobenzenes as Formally Electrophilic Components2.1 Palladium Catalysis2.2 Nickel Catalysis2.3 Copper Catalysis2.4 Cobalt Catalysis3 Azobenzenes as Formally Nucleophilic Components3.1 Palladium Catalysis3.2 Copper Catalysis3.3 C–H Activation Reactions4 Azobenzenes as Ligands in Catalysts5 Diazocines5.1 Synthesis5.2 Cross-Coupling Reactions6 Conclusion
