Summary: A new approach using conjugated microporous polymers (CMPs) to coat silica microparticles for removing organic compounds, especially pharmaceuticals, from waterbodies is presented. The CMPs were generated with different monomers and coupled to 1,3,5-triethynylbenzene (TEB) via Sonogashira coupling. The resulting coatings were adjustable in polarity and functionality, and had increased accessible surface area compared to bulk materials. The aniline-based CMP showed the highest adsorption capacity for the model drug diclofenac.

Summary: Since their discovery in 2007, conjugated microporous polymers (CMPs) have been developed for various applications. However, the insolubility and poor processability of CMPs due to their rigid structure limit their usability. Therefore, the development of CMPs with controllable structures on both micro- and macroscales has attracted great interest. Recent bottom-up synthesis strategies have been developed to obtain CMPs as thin films or hybrid materials, allowing for the span of different length scales. This review summarizes the recent advances in constructing CMPs into macroscale structures and discusses the fabrication techniques and implications of these structures in applications such as molecular separation, energy storage and conversion, photothermal transformation, sensing, and catalysis.

Summary: This study describes the synthesis of three conjugated microporous polymers (CMPs) incorporating ferrocene (FC) units with PDAT, TPA-NH2, and TPE-NH2 for supercapacitor electrodes. Among them, the TPA-FC CMP electrode exhibited extended discharge time, with a specific capacitance of 129 F g(-1) and capacitance retention of 96% after 5000 cycles. This superior performance can be attributed to the presence of redox-active triphenylamine and ferrocene units, as well as the high surface area and good porosity of the TPA-FC CMP.

Summary: In this work, a triketoenamine based dynamic covalent network was developed, which allows for easy construction of highly crosslinked and chemically reprocessable networks. The resulting polymer monoliths have high mechanical properties and can be recycled through aqueous solution-mediated monomer-network-monomer cycling. Furthermore, a catalyst-free and low-temperature reprogrammable covalent adaptable network was achieved. This design concept can be applied to the development of other novel vitrimers with high repressibility and recyclability, and contributes to the future design of sustainable polymers with minimal environmental impact.

Summary: Transition metal- and N-codoped carbon catalysts, with pyrrolic-N anchored dual metal centers, are designed and synthesized to replace Pt-based catalysts in oxygen reduction reaction. The coupling of Cu-N4 single-atom sites reduces the reaction energy barrier of pyrrolic-N-type Fe-N4 active site, leading to the successful synthesis of high-purity pyrrolic-N-type FeCu-N-C catalyst. The obtained catalyst exhibits a higher half-wave potential compared to Pt/C, indicating its potential as an effective catalyst in the field of oxygen reduction.

Summary: A facile strategy was developed to achieve heterogeneous and high-efficiency photocatalytic dehalogenation by tuning the exciton binding energy of conjugated microporous polymers. The integration of acceptors into the polymer scaffolds effectively minimized the exciton binding energy, suppressed charge carrier recombination, and facilitated charge transfer. The designed CMP-CSU11 exhibited superior photocatalytic dehalogenation efficiency, surpassing state-of-the-art catalysts and enabling a broad scope of substrates with excellent recyclability. This work provides an effective strategy to develop task-specific heterogeneous photocatalysts based on intramolecular charge transfer engineering.

Summary: MXene, a two-dimensional transition metal carbide, nitrides, and/or carbonitrides, shows great potential in various research fields due to its excellent conductivity, hydrophilicity, and abundant surface functional groups. However, challenges in aggregation and low stability greatly limit its applicability. MXenes can be synthesized through techniques such as exfoliation of MAX phases assisted by HF and nonHF materials, and bottom-up approaches utilizing vapor deposition and templating methods. MXene-based heterostructure composites have been investigated as potential nanomaterials for energy storage, and this article provides an overview of MXene synthesis and current developments in MXene-based heterostructure composites for electrochemical energy storage devices. Challenges and difficulties in the future design of MXene-based heterostructure composites are also discussed.

Summary: Triazine-based covalent organic frameworks functionalized by thiol and thioether (COFS-CH3/COFS-SH) were designed as a platform for specific binding with mercury ions based on Hard-Soft-Acid-Base theory. The COFS-CH3-modified carbon paste electrode exhibited exceptional performance (detection limit of 0.01 ppb; linear range of 0.1 to 1.0 ppb) and repeatability for electrochemical detection of trace mercury, even in real water samples. This innovative approach showcases the potential of covalent organic frameworks (COFs) for highly sensitive and selective detection of target analytes.

Summary: We present an efficient one-pot, two-step synthesis of a-difunctionalized alkynes and trisubstituted allenes by using benzal gem-diacetates and organozinc or-copper reagents in a sequential cross-coupling reaction without external transition metals. The use of propargylic acetates as intermediates allows for the selective synthesis of these valuable products. This method is characterized by easily accessible substrates, mild reaction conditions, a wide scope of applicability, and scalability in practical synthesis.
