Charge transport and near-infrared emission properties of semiconducting polymers

Research on semiconducting polymers is an interdisciplinary field that requires a wide range of knowledge ranging from polymer syntheses to electronics applications. Clarifying the correlations between chemical structures and physical properties leads to a better understanding of these materials. To find suitable application fields, it is necessary to repeatedly prepare polymer samples with slightly different chemical structures and evaluate their physical properties. The author's group started their research with the aim of developing high-performance semiconducting polymers that exhibited high charge carrier mobilities in thin film transistors, and this has recently been expanded to polymers that emit light in the near-infrared region.
