In this paper, we describe dual crown ether (CE)- and benzoxazine (BZ)-linked porous organic polymers (CE-BZ-POPs) incorporating pyrene (Py) tetraphenylethylene (TPE) units, synthesized through a multistep process involving Schiff-base formation, reduction, Mannich condensation, Sonogashira–Hagihara coupling, with their structures confirmed using Fourier transform infrared solid-state nuclear magnetic resonance spectroscopy. The presence of both CE BZ units in POPs has never been explored previously. Here, the underwent chemical transformations thermal ring-opening polymerization without curing agent or any catalyst. resulting bridges phenolic facilitated CO2 capture, mediated strong acid/base and/or intermolecular hydrogen bonding interactions; furthermore, bound strongly metal ions specific metal–ligand interactions, suggesting that these CE-BZ-POPs might be useful for wastewater treatment.

Nitrogen-doped carbon materials, characterized by abundant microporous and nitrogen functionalities, exhibit significant potential for dioxide capture supercapacitors. In this study, a class of porous organic polymer (POP) were successfully synthesized linking Cr-TPA-4BZ-Br4 tetraethynylpyrene (Py-T). The model benzoxazine monomers Cr-TPA-4BZ using the traditional three-step method [involving CH═N formation, reduction NaBH4, Mannich condensation]. Subsequently, Sonogashira coupling reaction connected Py-T monomers, forming Cr-TPA-4BZ-Py-POP. successful synthesis Cr-TPA-4BZ-Py-POP was confirmed through various analytical techniques. After verifying Cr-TPA-4BZ-Py-POP, carbonization KOH activation procedures conducted. These crucial steps led to formation poly(Cr-TPA-4BZ-Py-POP)-800, material with structure akin graphite. practical applications, poly(Cr-TPA-4BZ-Py-POP)-800 exhibited noteworthy CO2 adsorption capacity 4.4 mmol/g, along specific capacitance values 397.2 159.2 F g–1 at 0.5 A (measured in three-electrode cell) 1 symmetric coin cell), respectively. exceptional dual capabilities stem from optimal ratio heteroatom doping. outstanding performance holds promise addressing contemporary energy environmental challenges, making substantial contributions both sectors.

The synthesis of high-performance biomass benzoxazine resin by a solvent-free method is great significance for environmental sustainability and practical application in the industrial field. In this paper, biobased eugenol magnolol with additional allyl cross-linking sites were taken as phenol sources, 3-aminophenylacetylene alkynyl was used an amine source to prepare two monomers E-apa M-apa, corresponding cured resins poly(E-apa) poly(M-apa) prepared through certain curing process. comprehensive properties studied. results show that glass-transition temperature (Tg) high over 400 °C, which higher than (215 °C), well Tg values typical heat-resistant reported so far. At same time, initial thermal decomposition (Tdi) (441 °C) (373 showing better thermostability. addition, also exhibits mechanical including storage modulus tensile strength (5.03 GPa, measured at 25 48.0 ± 2.2 MPa, respectively) (3.93 GPa 37.5 1.5 respectively). Besides, performs flame retardancy. are based on combined action multiple rigid sources.

A biobased reprocessable and degradable polybenzoxazine vitrimer was prepared by introducing dynamic imine bonds. An aldehyde-containing benzoxazine monomer (VSA) synthesized through the Mannich reaction of vanillin, stearylamine, paraformaldehyde, then VSA reacted with 1,12-dodecanediamine to prepare an imine-containing (VSA-dda). The curing behaviors VSA-dda were characterized in situ Fourier-transform infrared spectroscopy differential scanning calorimetry. exchange bonds within cross-linked network (PVSA-dda) studied stress relaxation experiments. Due presence bonds, PVSA-dda could be reprocessed hot-pressing at 140 °C under 2 MPa. exhibited a shape memory property recover its original heating 100 °C. degradation performance investigated various conditions, results showed that degraded 29 min acidic solution tetrahydrofuran water 50
