“…Compared to previously reported ferrocene-containing porous polymers, the present polymers exhibit comparable porosity [ 28 , 29 , 46 , 47 ]. For example, Yamamoto reactions of 1,1′-dibromoferrocene and 5,10,15,20-tetrakis(4-bromophenyl)porphyrin or tetra( p -bromophenyl)methane resulted in two ferrocene-based conjugated microporous polymers (CMPs) with the S BET of 638 m 2 g −1 and 422 m 2 g −1 [ 31 ].…”

“…For example, Liu et al, reported ferrocene-based conjugated microporous polymers with intrinsic magnetism and the saturation magnetization of the materials can be adjusted by combining ferrocene with monomers with different conjugated degree [ 28 ]. By taking advantage of abundant ferrocene with high electron density and strong interaction with iodine molecules, a ferrocene-containing porous network FcTz-POP exhibited a significantly higher iodine vapor capacity than a ferrocene-free POP [ 29 ]. FcTz-POP can also served as a photocatalyst for methylene blue degradation under visible light irradiation at neutral pH [ 30 ].…”

Herein, we present two novel ferrocene-containing porous organic polymers, FPOP-1 and FPOP-2, by the Heck reactions of 1,1’-divinylferrocene with two tetrahedral silicon-centered units, i.e., tetrakis(4-bromophenyl)silane and tetrakis(4’-bromo-[1,1’-biphenyl]-4-yl)silane. The resulting materials possess high thermal stability and moderate porosity with the Brunauer–Emmer–Teller (BET) surface areas of 499 m2 g−1 (FPOP-1) and 354 m2 g−1 (FPOP-2) and total pore volumes of 0.43 cm3 g−1 (FPOP-1) and 0.49 cm3 g−1 (FPOP-2). The porosity is comparable to previously reported ferrocene-containing porous polymers. These materials possess comparable CO2 capacities of 1.16 mmol g−1 (5.10 wt%) at 273 K and 1.0 bar, and 0.54 mmol g−1 (2.38 wt%) at 298 K and 1.0 bar (FPOP-1). The found capacities are comparable to, or higher than many porous polymers having similar or higher surface areas. They have high isosteric heats of up to 32.9 kJ mol−1, proving that the affinity between the polymer network and CO2 is high, which can be explained by the presence of ferrocene units in the porous networks. These results indicate that these materials can be promisingly utilized as candidates for the storage or capture of CO2. More ferrocene-containing porous polymers can be designed and synthesized by combining ferrocene units with various aromatic monomers under this strategy and their applications could be explored.

“…Firstly, the abundant phenyl ring and nitrogen atoms are considered as specific binding sites for iodine molecule. [21] More importantly, TAPM is a common chemical raw material, which is widely used in the industrial production of polyisocyanate adhesive, providing a good precondition for industrial production. According to the literature, the three-dimensional structure can be formed by combination of trifunctional-bifunctional monomers or trifunctional-trifunctional monomers.…”

Designing a strategy for easy fabrication of amorphous porous organic polymers (POPs) with regularly nanospherical structure using common chemical raw materials is highly imperative to promote the practical application for iodine capture. Uniform covalent organic nanospheres (CONs), defined as CON-TT, were easily prepared at room temperature via a Schiff base condensation reaction of tri(4aminophenyl) methane (TAPM) and terephthalaldehyde (TPA) catalyzed by acetic acid. The obtained CON-TT exhibits a uniform nanospherical shape, high specific surface area, effective imine sorption sites and abundant benzene rings. An excellent reversible iodine adsorption capacity of 4.80 g g À 1 is achieved, which can be attributed to the hybrid of physisorption and chemisorption process. We anticipate that this work can provide general guidance for the industrial large-scale preparation of other CONs for iodine capture.

Redox‐active porous polymers are promising electrode materials due to various advantages including high specific surface area and porosity, facile synthesizing route, and excellent chemical and thermal stability. Herein, a simple and cost‐effective Schiff base reaction was used to prepare the ferrocene (Fc) containing porous organic polymer (POP) through the formation of a C‐N bond between melamine and 1,1′‐diacetylferrocene. After successful preparation of the Fc‐POP, Fc‐POP/PANI nanohybrid was prepared by the hybridization of synthesized redox‐active polymer with polyaniline (PANI) as a conductive polymer. Finally, the CNT (carbon nanotube)‐containing nanocomposites were prepared by adding various amounts of the CNT to Fc‐POP/PANI nanohybrid. All as‐prepared electrode materials were thoroughly characterized with usual analyses. The Fc‐POP/PANI/CNT20 revealed a high specific capacitance of 494 mAh g−1 at 2.5 A g−1 and excellent charge storage retention (92.1%) over 5000 cycles. Also, the fabricated symmetric cell exhibits a high energy density of 76 W h kg−1 and a high‐power density of 5840 W kg−1.
