Abstract

A simple electrochemical method of cyclic voltammetry (CV) was exploited to detect the cross-linking process of hybrid large-compound vesicles (LCVs) bearing electrochemically reactive ferrocene group inside. Results indicated that the CV behavior of LCVs deposited electrode was relative to the cross-linking degree of LCVs. It was found that oxidation peak potential became more positive and diffusion rates of electroactive species became smaller after the addition of triethylamine into LCVs solution with increasing time in few days. This showed that the increasing of cross-linking degree for LCVs hindered the electron transport of charge transfer between the neighboring active sites. Our studies will benefit the understanding and the control of the gelation process of hybrid LCVs for potential application in encapsulation and drug delivery.
