| 20110028676 | Molecular Actuators, and Methods of Use Thereof - The synthesis of thiophene based conducting polymer molecular actuators, exhibiting electrically triggered molecular conformational transitions is reported. Actuation is believed to be the result of conformational rearrangement of the polymer backbone at the molecular level, not simply ion intercalation in the bulk polymer chain upon electrochemical activation. Molecular actuation results from π-π stacking of thiophene oligomers upon oxidation, producing a reversible molecular displacement that leads to surprising material properties, such as electrically controllable porosity and large strains. The existence of active molecular conformational changes is supported by in situ electrochemical data. Single molecule techniques have been used to characterize the molecular actuators. | 02-03-2011 |
