“…Porous organic polymers (POPs) with high stability, low skeleton density, tunable porous structures and easy synthesis are an intriguing platform for incorporating homogeneous metal/ligand molecular catalysts into heterogeneous supports [42][43][44][45]. One particular advantage of POPs is the range of possible chemical functionality within the porous framework.…”

Solid supports functionalized with molecular metal catalysts combine many of the advantages of heterogeneous and homogeneous catalysis. A (NNN)Ru-incorporated porous organic polymer (POP-bp/bbpRuCl3) exhibited high catalytic efficiency and broad functional group tolerance in the C–C cross-coupling of secondary and primary alcohols to give β-alkylated secondary alcohols. This catalyst demonstrated excellent durability during successive recycling without leaching of Ru which is ascribed to the strong binding of the pincer ligands to the metal ions.

“…Recent advances have shown the Among iron based organic molecules, ferrocene is quite stable under ambient conditions and is an interesting organometallic compound due to its high reactivity that provides pathways for easy functionalization, promoting several substituted materials, particularly through a direct Friedel-Crafts reaction [8]. It is known that polymers containing ferrocene in their backbone usually involve the covalent attachment at both cyclopentadienyl rings via divalent 1,1 -ferrocenylene (or ferrocenediyl) units within the main chain [9]. The incorporation of covalently bounded ferrocene (see Figure 1b) into a polymer can be performed in two ways: (i) bottom-up, where the polymerization is from ferrocene and phenol, and (ii) post-synthetic modification, which consists of the addition of ferrocenediyl moieties into the already formed polymer backbone.…”

Ferrocene-Based Porous Organic Polymer (FPOP): Synthesis, Characterization and an Electrochemical Study

Ferrocene-based porous organic polymers (FPOPs) were prepared from phenol-formaldehyde polymer (Bakelite) and phenol as starting materials; and two possible mechanisms for polymerization were discussed. Solid-state 13C CP-MAS NMR, FTIR, powder XRD, elemental analysis and ICP (Fe, Na, B) were performed to characterize the prepared materials. The two synthetic approaches produced polymers with different pore sizes: the FPOP synthesized through Bakelite presented a higher surface area (52 m2 g−1) when compared to the one obtained by the bottom-up polymerization from phenol (only 5 m2 g−1). Thermogravimetric analysis confirmed the thermal stability of the material, which decomposed at 350 °C. Furthermore, cyclic voltammetry (CV) of the new FPOP on modified electrodes, in ACN and 0.1 M TBAP as an electrolyte, showed fully reversible electron transfer, which is similar to that observed for the ferrocene probe dissolved in the same electrolyte. As a proof-of-concept for an electrochromic device, this novel material was also tested, with a color change detected between yellow/brownish coloration (reduced form) and green/blue coloration (oxidized form). The new hybrid FPOP seems very promising for material science, energy storage and electrochromic applications, as well as for plastic degradation.

“…Porous organic polymers (POPs), which are constructed by organic building blocks via covalent bond, have shown potential applications in heterogeneous catalysis. [17][18][19][20] This is not only due to their good physical and chemical stability, high surface area and porosity, but also the intriguing functionalities and diverse synthetic strategy. To date, several metal salen based POPs have been reported as heterogeneous catalysts.…”

Most cross-linked polymers with integrated active sites in the network have poor flexibility, which inhibits their applications in catalysis involving a cooperative activation pathway. Herein, a flexible organic polymer with high concentration of salen ligand in the network (SOP) was successfully synthesized by the reaction of meso-1,2-diphenylethylenediamine and 1,3,5-tris(3'-tert-butyl-4'-hydroxy-5'-formylphenyl)benzene. The post-synthesis coordination with Co II followed by further oxidation results in the formation of SOPÀ CoÀ OTs. The large amounts uptake of benzene of SOP and variation of the BET surface area after coordination with different metal cations confirmed the network flexibility. Consequently, SOPÀ CoÀ OTs could efficiently catalyze the epoxides hydration to afford turnover frequency up to 2400 h À 1 via cooperative activation. Furthermore, SOPÀ CoÀ OTs works cooperatively with Amberlyst-15 in the hydration of phenylacetylene to afford higher yield than homogeneous Co-salen. Our primary results suggest the potential applications of flexible polymer catalysts in reactions involving cooperative activation pathway.
