제목 Monodisperse and sequence-defined conjugated polymers
초록 Synthetic polymers without distribution in their molecular weight and sequence attract recent interests. Conjugated polymers having discrete molecular weights and defined sequences can be model systems to understand the structure-property relationships of one-dimensional synthetic metals. In addition, these polymers having atomically precise structures could serve as new optoelectronic materials of which the physical and chemical properties were finely tuned for applications. The cross-convergent approach is a step-economical alternative to the solid-phase synthesis of sequence-defined polymers. In this talk, we show that polythiophene composed of a large discrete number of monomers connected in absolutely defined sequences can be synthesized by the cross-convergent method. The resulting monodisperse and sequence-defined polythiophenes can be used as valuable building blocks for constructing block copolymers and conjugated polymer networks.
