Three novel redox-active percec-type dendrons were synthesized by mucleophilic substitution reaction of 11-bromoundecyl ferrocene and substituted benzoate.All the resultant ferrocenyl-modified dendrons were confirmed through FT-IR,NMR,and elemental analysis,etc.Furthermore,the thermal properties and electrochemical behavior of these dendrons were monitored with thermogravimetry analysis (TG),differential scanning calorimetry (DSC),polarized optical microscope (POM),and cyclic voltammetry (CV).Abound phase behavior and reversible electrochemical redox reaction process in the DMF solution of these dendrons was observed.
