Recent Advances in Functionalized Cycloparaphenylenes: From Molecule Design to Applications

Abstract

Cycloparaphenylenes (CPPs), which feature a radial π-system, have attracted considerable attention owing to their size-dependent photophysical properties and a distinctive curved π-conjugated cavity. By incorporating of aromatic systems beyond benzene enable precise tuning of their optoelectronic properties to meet specific requirements in supramolecular chemistry and materials science. In this review, we systematically summarize synthesis, properties, and functional applications of CPP derivatives in chiral materials, supramolecular chemistry, and photoelectric devices. It is anticipated that this review will provide valuable insights for researchers working on CPP derivatives and carbon nanohoops, and contribute to the advancement of synthetic chemistry, materials chemistry.
