چکیده انگلیسی
Novel dendritic triphenylamine substituted fullerene as a rigid scaffold for electropolymerization have been prepared through cycloaddition reactions. Oxidative electrochemical polymerization of the dendritic molecules leads to thick freestanding fullerene/polytriphenylamine composite films. Due to their porous properties that allow n-Bu4NBF4 and n-Bu4NClO4 migrating in and out of the electrochemical deposition (ECD) layers, the films are highly electrochemically active with amphoteric properties. However, the fullerene reduction can be swept out and become silent after a high reduction potential of -2.4 V being applied to the film. If one considers the status before being treated by a high reduction potential as “1” that could be read out by the fullerene reduction currents, and the status after being treated as “0”, in which the reduction current is silent, information of “1” or “0” could then be written on the plate through electrochemistry. Since the channel of anodic oxidation of the polytriphenylamine component still maintains electrochemically active after the reduction shock, the anodic oxidation current can be used as reference for alignment.
