Abstract
The DC polarograms of an oligomer with four repetitive units of ‘extended viologen’ yield in part irregular current fluctuation. The analysis of the current–time transients at different potentials confirms the periodicity, the period doubling and transfer to chaos. The periodicity doubling obeys the universal route to chaos. The estimated value of the Feigenbaum constant 4.68 is very close to the theoretical value δ = 4.6692...Keywords
