Abstract

Electrochemical polymerization of the N-substituted pyrrole monomer

methyl (S)-(+)-2-(1H-pyrrol-yl) propionate in a chiral medium with (S)-(+)-camphor-10-sulfonic acid ((S)-(+)-CSA) or (R)-(-)-camphor-10-sulfonic acid ((R)-(-)-CSA) The obtained polymer films were characterized by cyclic voltammograms (CV)

X-ray photoelectron spectroscopy (XPS)

infrared

Raman

circular dichroism (CD) spectroscopies and scanning electron microscopy (SEM) The enantioselective recognition properties of polymer were also investigated in the presence of enantiomers of eamphorsulfonic acid as supporting electrolyte and doping agent Chiral alkyl N-substituted polypyrrole micro-ribbons were generated electrochemically and stand upright on the working electrode surface．The ribbons have alength of 100～200μm．a width of 20～50μm and athickness of 3～5μm．
