Design of carbon nanotube-polymer frameworks by electropolymerization of SWCNT-pyrrole derivatives.

Single-walled C nanotubes (SWCNTs) were functionalized by electropolymerizable pyrrole groups following covalent and noncovalent strategies. The covalent pyrrole grafting was carried out by ester formation between pyrrole alc. and chem. oxidized SWCNT. The strong $π$-interactions between pyrene and SWCNT were exploited for the noncovalent adsorption of a new pyrene-pyrrole deriv. on the pristine nanotube surface. The pyrrole-ester-SWCNT was solubilized in THF and electropolymd. by controlled potential electrolysis at 0.95 V. The pyrene-pyrrole SWCNT was spread on an electrode surface and electropolymd. in its adsorbed state at 0.95 V in MeCN. The reinforced nanostructured polypyrrole SWCNT-framework was studied with SEM.
