Perylene bisimides - Advanced synthesis and photoelectric applications

This review offers an overview of the synthesis and photoelectric applications of various derivatives of perylene bisimides at different positions, spanning from the imide to bay positions, achieved over the past decade. The synthesis of PBIs involves several routes, including classical methods such as condensation reactions and modern strategies like click chemistry and photochemistry. These methods offer control over the molecular structure, allowing for tailored properties suited for specific applications. In photoelectric applications, PBIs exhibit exceptional characteristics like exceptional photostability, strong absorption within the visible spectrum, and effective charge mobility. These attributes render PBIs excellent candidates for applications such as organic photovoltaics, OLEDs, sensors and organic field-effect transistors. In this review we delve into the development of novel synthetic methodologies, highlighting recent advances in synthetic tools such as C-C coupling and C-H activation. Additionally, the review explores the diverse photoelectric applications of these derivatives, encompassing optical properties, redox behavior, molecular selfassembly, and photo-induced electron transfer characteristics.
