Selective Adsorption of Organic Light Emitting Molecule on PANI Microstructure

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.
