Remarkably high electrochemical charge uptake for modified electrodes of polyacetylene molecular wires encapsulated within zeolites and mesoporous MCM-41 aluminosilicate
Heavy loaded samples of polyacetylene and polypropyne incorporated within zeolites or MCM-41 were obtained by in situ polymerisation of the corresponding alkynes on Ni2+-exchanged aluminosilicates. Charge uptakes were obtained as high as 250 C g(-1) (the theoretical amount for complete polyacetylene oxidation), the highest ever reported for a zeolite modified electrode. Voltammetric peaks were however irreversible and extensive degradation occurs. (C) 2002 Published by Elsevier Science B.V.
