Abstract
We have synthesised a series of polyquinoxalines and model oligomers. This paper concentrates on optical and electrical properties of the fi ve-ring dihydrotetra-azapentacene. When it is doped via electron and/o r proton transfer, a variety of charged species are formed. Cyclic vol tammetry reveals three oxidation states, discussed here in relation to conductivity data using HCl gas doping, optical absorption spectra, a nd preliminary ESR work.
