Abstract
AbstractBipolar electrochemistry could be regarded as a powerful approach for selective surface modification due to the beneficial feature that a wirelessly controllable potential distribution on bipolar electrodes (BPEs). Herein we report a bipolar electrolytic micelle disruption (BEMD) system for the preparation of shaped organic films. A U‐shaped bipolar electrolytic system with a sigmoidal potential gradient on the BPE gave gradient‐thin films including various interesting organic compounds, such as a polymerizable monomer, an organic pigment and aggregation induced emission (AIE) molecules. The gradient feature was characterized by UV–Vis absorption, thickness measurements and surface morphology analysis. Corresponding patterned films were also fabricated using a cylindrical bipolar electrolytic setup that enables site‐selective application of the potential on the BPE. Such a facile BEMD approach will open a long‐term perspective with respect to organic film preparation.
