This study explores the synthesis of a new squaraine-quinoline-graphene hybrid foruse in organic photovoltaics (OPV). The goal of this project is to research the effect ofsquaraine-quinoline based dye attached to exfoliated graphene using π-π-stacking.To achieve this several novel compounds have been synthesized resulting in a dyethat was successfully attached to graphene. The dye (9) were analyzed usingdifferential pulse voltammetry, UV-VIS and photoluminescence spectroscopy.The final dye (9) was synthesized with a yield of 57%, HOMO and LUMO levels wereapproximated to 5,31 eV and 3,75 eV respectively with a bandgap of 1,55 eV.
