Organic two-dimensional materials have garnered widespread attention due to their well-defined structures, structural diversity, and rich electronic effects, demonstrating significant application potential across various fields. Atomic-level manipulation of the structures of organic two-dimensional materials has been a primary strategy for enriching and optimizing their properties. The introduction of heteroatoms often significantly affects their electronic structure, thereby endowing these materials with novel and unique properties. Boron atoms, due to their electron-deficient nature, have been extensively studied in luminescent materials, semiconductor materials, and chemical sensing materials. Consequently, boron-containing organic two-dimensional materials are also believed to be promising as a new class of materials with excellent optoelectronic and chemical activities. This article collates and summarizes the preparation and property studies of three types of boron-containing organic two-dimensional materials in recent years.

This analysis revealed the alterations in the pore structure of large organic molecules in coal during the process of coal pyrolysis. Nine models of macromolecular structures in coals, representing distinct coal ranks, have been built. The research results show that along with the increasing coal rank, the average microporous volume of medium rank coal is 0.

In this study, we have proposed an electrochemiluminescence (ECL) signal amplification system which is based on two-dimensional (2D) flower-like CdS@Co/Mo-MOF composites as a co-reaction accelerator of the g-CN/SO system for ultrasensitive detection of chlorpromazine hydrochloride (CPH). Specifically, the 2D flower-like Co/Mo-MOF with mesoporous alleviated the aggregation of CdS NPs while simultaneously fostering reactant-active site contact and improving the reactant-product transport rate. This allowed the material to act as a novel co-reaction accelerator, speeding up the transformation of the SO into SO and enhancing the cathodic ECL emission of g-CN.

Silicone gel, used in the packaging of high-voltage, high-power semiconductor devices, generates bubbles during the packaging process, which accelerates the degradation of its insulation properties. This paper establishes a testing platform for electrical treeing in silicone gel under pulsed electric fields, investigating the effect of pulse voltage amplitude on bubble development and studying the initiation and growth of electrical treeing in a silicone gel with different pulse edge times. The relationship between bubbles and electrical treeing in silicone gel materials is discussed.

Alkali element doping has significant physical implications for two-dimensional materials, primarily by tuning the electronic structure and carrier concentration. It can enhance interface electronic interactions, providing opportunities for effective charge transfer at metal-organic interfaces. In this work, we investigated the effects of gradually increasing the level of K doping on the lattice structure and electronic properties of an organometallic coordinated Kagome lattice on a Ag(111) surface.

Two-dimensional (2D) polymer network monolayers with novel block architectures were fabricated via sequential copolymerization within a pillared-layer metal-organic framework (MOF) that served as the reaction template. The MOF provides a confined 2D nanospace, restricting the crosslinking copolymerization of vinyl monomers to two dimensions. Sequential crosslinking copolymerization of methyl methacrylate and styrene, regulated by the reversible addition-fragmentation chain transfer (RAFT) process, resulted in the formation of 2D block architectures with 'patchy' domains consisting of crosslinked poly(methyl methacrylate) and polystyrene segments.
