Aim of the subproject: Aim of the project is the synthesis of new monomers for low-bandgap polymers. Specifically, new routes towards 2-phenyl-benzotriazoles will be investigated and these monomers copolymerized with metallated thiophene derivatives. Additionally, new thiophene monomers will be synthesized. A part of the programm includes also the synthesis and investigation of new (cyclic) oligomer structures as donor component in OPV devives.
