Due to the host-guest interaction between cucurbit[10]uril and perylenebisdiimide (PDI) derivatives, DNA-PDI conjugates can achieve morphological shifting from spherical micelles to two-dimensional nanosheets. The competitive binding between the guest 3,5-dimethyl-1-adamantanamine hydrochloride and PDI units induces the reversibility. The 2D nanosheets can act as addressable templates to organize the functional molecules through DNA hybridization.
