A truly novel strategy for fabricating reducible supramolecular assemblies based on the host–guest interaction between cucurbit[8]uril (CB[8]) and methyl viologen (MV) is reported. The anticancer drug doxorubicin is loaded into the assemblies and a reducing agent Na2S2O4 can be used to successfully trigger release of drugs because of the redox chemistry of MV.
