Abstract Arylated anthraquinone derivatives of different sizes and different π-basicities have been prepared, and the electrochemical behaviour of these substances has been studied on screen printed graphite electrodes in the three room temperature ionic liquids (RTILs), 1- butyl-3-methylimidazolium hexafluorophosphate ([C 4 MIM][PF 6]), 1-hexyl-3- methylimidazolium hexafluorophosphate ([C 6 MIM][PF 6]) and 1-octyl-3- ...
