Selective Adsorption of Organic Light Emitting Molecule on PANI Microstructure

Abstract

Abstract: We developed a method for patterning organic light emitting molecules with polyaniline(PANI) \{microstructure\} as a template. Its microstructure was characterized with atomic force microscopy(AFM). PANI microstructure was treated with O₂ plasma at low power and short time to get the hydroxyl groups on the silicon substrate, meanwhile, which can minimize the impact on PANI structure. We modified the \{structure\} with fluoro\|silane reagent through self\|assembly to make substrate bearing different surface energies on \{different\} areas. Finally, we deposited dyes on substrate by evaporation. The results show that the dyes on the \{fluoro\|silane\} monolayer can move toward the PANI structure during storage duration and form the structure of organic light emitting molecules.
