摘      要：Host-guest supramolecular gels were developed via the self-assembly of inclusion complexes(ICs) ofβ-cyclodextrins/phenylboronic acid gelator(PBA).Salts and current were involved in the self-assembly to stabilize the host-guest *** stability of the gels was greatly improved after salts were *** stable time of gels was extended from 2.5 h to 120 h with the addition of NH_4 NO_3 at the concentration of 2.5×10^(-2) g/*** morphology of the gel was affected by the concentrations of NH_4NO_*** images revealed that the gels were three-dimensional nanofibrous networks,the sizes of fibers decreased with decreasing NH_4NO_3 concentrations,which affected the stability of gels,further proved by the rheological properties of *** stable gels were obtained with current stimulation,the stable time of the gel was increased from 2.5 h to 55 h with current by adding NaBF_*** current also exhibited significant influence on the aggregation as the voltage varied(0-500 mV) with a constant concentration of *** result showed the self-assembly process of host-guest gel could be well controlled via the addition of salts and current to desired morphology and stability.
