A simple fluorescent molecular CPDB with excitation-wavelength-dependent

emission resulting from dynamic protonation in aqueous solution under acidic

conditions is synthesized. A hierarchical supramolecular self-assembly system with

controllable morphology has been accomplished, including 1D worm-like

nanoribbons, 2D rectangular nanoplates, and 3D microscale polyhedrons, through

different host-guest complexation modes between CPDB and cucurbit[8]uril at

different binding ratios, which can be applied to secondary encryption.
