Host-Guest Chemistry in Binary and Ternary Complexes Utilizing -Conjugated Carbon Nanorings
ChemPlusChem(2024)
Abstract
The carbon nanorings, possessing a radial pi system, have garnered significant attention primarily due to their size-dependent photophysical properties and the presence of a unique curved pi-conjugated cavity. This is evidenced by the rapid proliferation of publications. Furthermore, the integration of building blocks into CPP skeletons can confer [n]CPPs with novel and exceptional photophysical and electronic characteristics, as well as chiral properties and host-guest interactions, thereby augmenting the diversity of [n]CPPs. Notably, the curved pi surface structures and concave cavity of carbon nanorings enable them to host aromatic or non-aromatic guests with a complementarily curved surface, resulting in interesting binary or ternary complexes. This review provides a comprehensive treatment of literature reports on binary and ternary complexes, focusing on both their host-guest interactions and properties. It is important to note that the scope of this review is limited to host-guest chemistry in binary and ternary complexes based on pi-conjugated carbon nanorings. Carbon nanorings with unique curved pi-conjugated cavity are able to host aromatic or non-aromatic guests with a complementarily curved surface, resulting in the formation of interesting binary or ternary complexes. This review comprehensively covers literature reports on binary and ternary complexes based on pi-conjugated carbon nanorings, providing a thorough treatment of the subject.image
