We compare the stability of [n]cycloparaphenylene ([n]CPP)-based host–guest complexes with Li+@C60 and C60 in the gas and solution phase. Our experiments reveal a significant increase in stability for the complexes featuring [9–12]CPP with Li+@C60.
We predicted and verified the intramolecular charge transfer and solvatochromic behavior of carboxymethyl ester-functionalized [10]cycloparaphenylene derivatives, clarifying their optical properties.
DFT calculations proved that buckybowls can be stabilized in a cycloparaphenylene host through multi-site CH–π interactions and the restrictive buckybowls display novel reactivity distinct from that in their free state.
[2]Catenanes comprising identical binding sites are an excellent platform to study the unusually slow kinetics of concave–convex π–π interactions.
Nanoscaled 2D and 3D carbon structures with closed curved π-surfaces are of relevance in the development of desirable building units for materials science, where the connection between small and larger molecular systems is revealed.
