Crystal and optimized structures of host–guest complexes 1•5EO and 1•CE, respectively. a X-ray crystal structure of 1•5EO and b its space-filling representation (the peripheral substituents of 1 are replaced by hydrogen atoms for clarity). c Highlighted host–guest and guest-guest interactions of 1•5EO in the cavity (red and blue dashed lines are CH-π and hydrogen-bonding interactions, respectively). d Optimized structure of 1•CE (the peripheral substituents of 1 are replaced by hydrogen atoms for clarity)
