A series of four 1 : 1 host–guest supramolecular complexes of [n]CPPs and C₇₀ have been analyzed by Raman spectroscopy in the solid state and complemented with the analysis of their spectroscopic responses under mechanical and thermal stresses. By following the frequency behaviour of the G and RBM modes we have found that [10]CPP in the [10]CPP@C₇₀ complex displays a more “ordered” structure. However, in [11]CPP@C₇₀, the nanoring becomes oval-shaped with closer contacts with the C₇₀ poles and less conformational restriction in the flattened region. By mechanical and thermal stresses we are able to modify the lying conformation of [10]CPP@C₇₀ towards a standing orientation. [11]CPP@C₇₀ resists pressure changes, although it tends to shift from the standing to the lying orientation by heating. As for the crystal cell, the [n]CPPs occupy the residual empty spaces while the main crystallographic positions are reserved for C₇₀. These are new examples of the impressive adaptability of the [n]CPP molecules to different physico-chemical environments, a chameleon-like property which reveals the delicate equilibrium provided by cyclic conjugation and ring strain.
