Summary: | Functional materials composed of Boron‐chalcogenophene conjugates have emerged as promising ensemble featuring commendable optoelectronic properties. This review describes the categories, synthetic routes and optoelectronic applications of a range of boron‐chalcogenophene conjugates. Conjugation and linking of different types of tri‐ and tetra‐coordinated boron moieties with chalcogenophenes have remained an important strategy for constructing a range of functional materials. Synthetic protocols have been devised to efficiently prepare such chemically robust conjugates, often exhibiting a myriad of photophysical properties, redox capabilities and also solid‐state behaviors. Tin‐boron and silicon‐boron exchange protocols have been efficiently adapted to access these boron‐chalcogenophenes. Few other commonly used methods namely, hydroboration of alkynes as well as electrophilic borylations are also mentioned. The chemical and electronic properties of such boron‐chalcogenophene conjugates are directly influenced by the strong Lewis acid character of trivalent boranes which can further alter the intra‐ and inter‐ molecular Lewis acid‐base interactions. Apart from the synthetic protocols, recent advances in the application of these boron‐chalcogenophene conjugates towards analyte sensing, organic electronics, molecular switches and several other aspects will be discussed in this review.
