Non-alternant cyclo-penta fused polycyclic aromatic hydrocarbons: Efficient structural elements to achieve n-type characteristics in conjugated polymers

Boek - Dissertatie

The aim of the research presented in this dissertation is the design and development of a new class of n-type conjugated polymers. This aim is motivated by the expectation that such a class of materials potentially can Chapter 2 describes our search for and discovery of a novel class of n-type conjugated polymers. The synthesis and characterization of the first representative of this class of polymers, i.e. poly(fluoranthene vinylene) PFV, is presented. In chapter 3, side chains are attached to the fluoranthene groups present in the PFV backbone. The major objective for this functionalization with alkyl groups is to improve the solubility and processability. In chapter 4, in a special way it is proven that the nonalternant character of fluoranthene is responsible for the highly desirable ntype behavior. Finally, chapters 5 and 6 focus on our efforts to develop and characterize also other material systems containing conjugated polymers. Chapter 5 presents a fundamental study of the radical polymerization behavior of PPV and demonstrates the reality of copolymer architectures. Such architectures are expected to facilitate the formation of nano-structured morphologies in thin films. Finally, chapter 6 focuses on the opto-electronic characterization of a selection of typical novel low band gap conjugated polymer systems. Finally towards the end of this thesis general conclusions, perspectives and summaries in Dutch and English will be presented.
