Cycloparaphenylenes (CPPs): An Overview of Synthesis, Properties, and Potential Applications

Abstract

Abstract Cycloparaphenylenes (CPPs) have attracted significant attention from theoretical, synthetic, supramolecular and material chemists owing to their aesthetical structures. Since Jasti and co‐workers reported the landmark synthesis of [9]CPP, [12]CPP and [18]CPP, the past ten years have witnessed a remarkable burst in the development of CPP research, from synthetic methodologies to the applications in optoelectronic devices. In this Focus Review, we highlight the representative synthetic strategies to CPPs and attempts on bottom‐up synthesis of carbon nanotubes (CNTs), and mainly focus on the optoelectronic properties studies of functionalized CPPs as well as heteroatoms doped CPP derivatives. Additionally, the potential applications of CPP derivatives in material science are discussed.
