“…In fact, the BDP based CMP have been reported as good photocatalyst for oxidation of thioanisoles to methylphenyl sulfoxide in 2‐ ethoxyethanol . A series of POPs with numerous BDP units were developed and their abilities to generated O 2 were dependent on the molecular isomerization and spacer between the dimeric BDP building block . While the surface areas showed little effect on this ability.…”

Different kinds of porous organic polymers (POPs) bearing 4,4‐difluoro‐4‐bora‐3a,4a‐diaza‐s‐indacene (BDP) fluorophores have been developed to generate singlet oxygen upon light illumination. Herein, four imine‐linked POPs were prepared by copolymerization of amine and aldehyde with different ratios of di‐aldehyde A1 and A2. The POPs were investigated by a combination of techniques such as solid 13C NMR, FTIR, and nitrogen absorption–desorption isotherms and electronic microscopy. The results demonstrated that these POPs were prone to form hierarchical porous architectures. Scanning electron microscopy and transmission electron microscopy images revealed that the spherical morphologies showed different roughness, that is, BDP‐POPs with more BDP aldehyde A2 presented rougher surface. Finally, these POPs were used to generate singlet oxygen (1O2) monitored by 1,3‐diphenylisobenzofuran and bioimaging in HeLa cells. Our results indicated that the ability to generate 1O2 is dependent on the amount of BDP. © 2017 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2018, 56, 319–327

“…This fast iodine uptake is comparable to the action of previously reported alkyne-and phenyl ring-rich materials. [30] In COTs, the presence of phenyl rings, triple bonds, and a cationic surface provides multiple docking sites for iodine molecules and leads to fast capture. In the vapor phase, adsorption experiments were performed using an excess amount of solid iodine, which was heated to 40 8C under ambient pressure.…”

Adjustment of the morphology of covalent organic nanomaterials is a challenge but can be achieved by perturbing the planarity of the monomers used as core moieties in these polymers. Here we describe a templatefree Zincke reaction for the synthesis of covalent organic nanosheets (CONs) that stack several layers thick and of covalent organic tubes (COTs). Both materials contain the same viologen linker but different pyrene-based cores. Both polymeric materials are nanoporous, cationic, and highly stable in water, even in the presence of acid (1 M HCl) or base (1 M NaOH). Their porosity and ionic surfaces are responsible for high affinities and adsorption capacities for iodine vapor.Porous covalent organic polymers (COPs) are well known for their diverse applications in fields such as gas storage and separation, [1][2][3][4] catalysis, [5][6][7][8] sensing, [9,10] drug delivery, [11] and environmental remediation. [12] In order to design COPs with improved functionality, considerable research has been undertaken to understand the relationship between the morphologies and properties of these materials. [13][14][15] It has been observed that the morphology of COPs can be tuned by changing the symmetry of their constituent building blocks, but precise regulation of COP nanostructure remains a challenging task.Syntheses of covalent organic hollow tubes (COTs) and nanosheets (CONs) are of interest because their large surface areas facilitate the adsorption of small molecule guests. Porous, template-free COPs with uniform tube morphology have been used for device manufacturing [16] and catalysis, [17,18] but reports of the synthesis and application of this type of material remain scarce. Studies of covalent nanosheets are more prevalent, but, this type of material is obtained by either liquid phase exfoliation [19] or mechanical delamination, [20] and these two methods often result in low surface areas because the mechanical forces involved often cause pore blockage. In short, syntheses that rely on mechanical techniques for isolating nanosheets tend to be expensive and non-scalable and produce materials that have limited adsorption efficiency. Designing an efficient and green approach to the large-scale synthesis of porous CONs stacked several (or fewer) layers thick is an open challenge. [21] In general, porous COPs are synthesized from neutral building blocks, which limits the range of application for the materials. For example, neutral COPs are not optimal for the uptake of charged species, including toxic ionic guest molecules. To address this issue, we have begun to develop charged COPs that incorporate redox-active viologens and are capable of adsorbing iodine vapor, toxic dyes, and metal ions by anion exchange. [22,23] Despite their great potential, viologen-based COPs are still rarely documented in the literature, though Li et al. [24] have reported supramolecular organic frameworks (SOFs) that contain viologen struts and form in water.Herein, we report a one-pot, template-free solvothermal synthesis ...

Nitrogen-doped carbon-based materials including nanocarbons, graphene, and conductive polymers are impressive as supercapacitor electrodes. However, ultrahigh nitrogen contents, micropore dominated, and morphology evolving carbonaceous electrodes have not achieved until now which are crucial for supercapacitor. Herein, we prepare a novel fumaronitrile (FUM) derived covalent triazine framework (FUM-CTF) and activated it by using KOH at different temperatures to obtain the corresponding carbon materials, which were used as supercapacitor electrode materials. Specially, the FUM-700 (sample activated at 700 °C) possesses an excellent specific capacitance of 400 F g at a current density of 1 A g and considerable energy density over 18 Wh kg in KOH (6 m) aqueous electrolyte. In addition, this electrode shows 260 F g at a current density of 20 A g for charge/discharge operation. Furthermore, the FUM-700 electrode demonstrates extraordinary electrochemical stability with 97 % retention after 10 000 cycles at 10 A g . Ultrahigh nitrogen contents, the microporous structure, and the inner nanoparticle morphology work in concert to contribute to the superior electrochemical performance of FUM-700. Our work might give some hints to help design other high-performance nitrogen-containing supercapacitor electrode materials.
