Abstract

Four N-substituted pyrrole derivatives with oligo (ethylene glycol)-functionalization were synthesized and characterized by ¹H and ¹³C NMR and FTIR. Namely 2-[2-(1H-Pyrrole-1-yl)-ethoxy]-ethan- 1-ol, 1-{17-[(tetrahydro-2H-pyran-2-yl)oxy]-3,6,9,12,15-pentaoxaheptadecyl}-1H-pyrrole, 1,1’- bis(2-(2-(2 ((tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethyl)-1H,1’H-2,2’-bipyrrole and 1-(2,3,5,6,8,9,11,12,14,15-decahydrobenzo[b][1,4,7,10,13,16]hexaoxacyclooctadecin-18yl)-1H-pyrrole were electrodeposited from acetonitrile electrolytes by cyclic voltammetry on a platinum electrode. The deposited films were characterized by its electro polymerizable behaviour and deposited masses calculated from the evaluated charges of the reversible redox peaks of the polypyrrole systems. Overoxidation of the polypyrrole redox system potentials were determined and Li+ ion conductivity within the deposited film was determined by impedance spectroscopy.
