Recent Advance of 1,2-BN Heteroaromatics in China

Abstract

Polycyclic aromatic hydrocarbons (PAHs) and their derivatives are widely used in the field of organic optoelectronic materials, and the photophyscial properties of polycyclic aromatic hydrocarbons can be effectively modified by heteroatomic doping. By replacing carbon carbon (CC) units with an isoelectronic and isostructural boron nitrogen (BN) units, the electronic structure and intermolecular interactions of PAHs can be fine-tuned, resulting in new BN-heteroaromatics with unique optoelectronic properties and bioactivity. BN/CC isosterism can not only enrich the famlily of heteroaromatics but also promote their applications in the fields of optoelectronic, catalysis and biomedical applications. In particular, the researchers from China have engaged and promoted the development of boron/nitrogen-doped heteroaromaics, leading to some great results. The recent advance of 1,2-BN heteroaromatics in China from the chemistry perspective is summarized, including the synthetic development of 1,2-BN heteroaromatics, as well as their applications in variety of research fields. In the end, the development prospects of BN-heteroaromatics are pointed out. Through highlighting these advances of boron/nitrogen-doped heteroaromaics in China, it is hoped that more researchers will be interested in the synthesis and application of boron/nitrogen-doped heteroaromaics. It is also hoped that this review would stimulate the conversation and cooperation between the chemists and material scientists in the related fields.
