UV-Vis Absorption

UV-Vis absorption of of PTQ10 in film (as-cast film from PTQ10 solution in chlorobenzene on glass).

Cyclic Voltammetry

Cyclic voltammograms of the PTQ10 film on platinum electrode in 0.1M Bu4NClO4 in acetonitrile at a scan rate of 100 mV s−1.

The cyclic voltammograms (CV) measurements were recorded on Ossila Potentiostat by using a three-electrode system with platinum disc as the working electrode, platinum wire as the counter electrode, Ag/Ag+ electrode as the reference electrode with a scanning rate of 100 mV/s in a 0.1 M tetrabutylammonium perchloroate Bu4NClO4) solution. The potential of Ag/Ag+ reference electrode was internally calibrated by using ferrocene/ferroncenium (Fc/Fc+) as the redox couple.
