ABSTRACT
This chapter explains the studies on heteroatom-containing conjugated polymers. The development of conjugated polymers is a topic with high relevance. Unique optical, electric, and spintronic characteristics have been discovered from the conjugated polymers. The chapter illustrates the preparation of the emissive polymers and the control of their optical properties. In general, the brilliant emissions of conjugated polymers disappear by condensation. This fact means that optical properties should be lost in the solid or film states. These behaviors are called concentration quenching or aggregation-caused quenching (ACQ). The number-average molecular weights (Mn) and the molecular weight distributions of the polymers were evaluated bya size-exclusion chromatography with the standard polymers. The chemical structures of the polymeric products were characterized with the series of NMR measurements. In 2007, he moved to the Department of Polymer Chemistry, Graduate School of Engineering, Kyoto University, and in 2014, he was promoted to lecturer and then associate professor in2015.
