Photo‐Activated Emission and Chirality Transfer Based on Host–Guest Chemistry of a Motorized All‐Benzene Nanohoop

in 1:1 stoichiometric ratio. The formation of host-guest complexes decelerates the photo-isomerization processes of M[11]CPP and achieves photo-activated fluorescence emission of the host-guest systems. Furthermore, taking advantage of the intrinsic chirality of M[11]CPP, as well as the CH-π interactions between M[11]CPP and perylene, the chirality is transferred onto perylene, and circularly polarized luminescence is realized. This work not only provides a novel strategy for tuning the optical properties of cycloparaphenylenes through host-guest interactions but also demonstrates the potential of integrating molecular motors into macrocyclic systems to achieve dynamic control over molecular behavior.
