• Herein we present a systematic study of the influence of different alkyl chains in malonyl ester fullerene adducts with [10]cycloparaphenylene ([10]CPP]) and a tert‐butyl (tBu) ester‐substituted [10]CPP analogue. The association constants between the nanoring hosts and the fullerene guests were determined by fluorescence quenching experiments. The trends in association were rationalized by an interplay of repulsion arising from an extended volume and London dispersion as an attractive counterpart. The supramolecular assembly between substituted [10]cycloparaphenylene (s[10]CPP) and fullerenes was studied to investigate the subtle interplay of steric repulsion, conformation and attractive London dispersion interactions. For this, [10]CPP and a tert‐butyl ester‐substituted analogue were employed as host molecules whose fluorescence is quenched upon addition of C60 as well as alkyl malonyl ester‐substituted fullerenes.
