Hierarchically structured functionalizable mesoporous PEDOT-derived conductingpolymers

Chemically functionalizable carboxy group-containing mesoporous poly(3,4-ethylenedioxythiophene) (PEDOT) derivatives, C1-CT/PEDOT/PSS and C4-CT/PEDOT/PSS, with hierarchical particle morphology were prepared in the presence of sacrificial acid-labile ZnO/Zn(OH)2 hard template. The hard template could be effectively removed by acid etching. The electrical properties and surface texture of the mesoporous PEDOT derivatives were investigated. The chemical accessibility of the carboxy groups in the PEDOT materials was successfully demonstrated by conjugation with green fluorescent 5-aminofluorescein (AFL). AFL-conjugated AFL-C4-CT/PEDOT/PSS particles exhibited uniform green fluorescence under a fluorescence microscope.
