Facilitating Phase Transfer of Polymer Semiconductor in Mini-Emulsion Synthesis via Molecular Affinity Engineering |
| 초록 |
A synthetic approach has demonstrated to enhance coalescence during solidification of water-borne colloids so that thin and uniform film morphology can be realized. From theoretical study, it is shown that small-sized and uniform colloids are essential to minimize depletion energy between colloids and thus to enhance coalescence. Therefore, the synthesized polymer semiconductor is designed for better molecular affinity with surfactants, so that phase transfer of polymer can improved during mini-emulsion synthesis. This is achieved by substituting a Si atom to the branching C atom of the alkyl solubilizing group of a conventional polymer semiconductor. Such a chemical modification increases the volumetric portion of hydrophobic alkyl chains and thus enables higher solubility as well as hydrophobicity. As a result, the performance and reproducibility of organic field-effect transistors fabricated from water-borne colloids can be improved to similar as the case of organic solvents. |
