Two directional Pummerer cyclisations in a synthesis of dihydropyrroloindoledione based monomers for organic polymer photovoltaic devices

Student thesis: Master of Philosophy


There is a great demand for organic photovoltaic devices in harvesting solar energy to address the energy crisis. One recently discovered class of co-polymer of pie-conjugated organic polymer which shows great promise is the diketopyrrolopyrrole (DPP) and benzaodipyrrolidone (BDP). This report describes a two-directional synthesis of the novel dihydropyrroloindoledione (DPIP) monomers, which are structurally related to DPP and BDP. Work has focussed on the development of a two-directional approach to the monomers utilising a Pummerer-type cyclisation previously developed in the group.. Two DPIP-based polymers were synthesised using the monomers prepared during the project and their optical and electronic properties are also presented. Finally, work towards the synthesis of a new BDP monomer was initiated.
