Synthesis and Applications of Organic Borazine Materials

The past decade has marked a renewed interest in borazines and BN‐doped polycyclic aromatic hydrocarbons. This is predominantly because of new advances that have highlighted their potential in various applications, including gas separation and storage, organic (opto)electronics, catalysis, and as supramolecular systems. This review gives a critical overview of the most significant approaches to the synthesis of (substituted) B3N3 motifs and focuses on the discussion of those borazine‐doped carbon structures that have been developed for potential use in materials science applications. The borazine ring, while sharing geometric similarities with benzene, exhibits markedly different electronic properties. The incorporation of the borazine unit into carbon‐based frameworks facilitates the development of materials with adjustable properties. Such composite structures present unique characteristics, rendering them pivotal in applications such as gas storage and separation, catalysis, (nano)electronics, and (opto)electronics.
