제목 Odd-Even Effects of Alkyl Chain Spacer on the Electrical Performance of Diketopyrrolopyrrole-Based Polymer Semiconductors
초록 A series of diketo-pyrrolopyrrole-based polymer semiconductors with branched alkyl groups containing even or odd numbers of linear spacer groups are synthesized to investigate the relationship between molecular structure and electrical properties. To date, however, very little is known about an odd-even effect of alkyl side chains of conjugated polymers due to their relatively disordered or complex conformation compared with small molecules. Herein, odd-even effect of alkyl side-chain length in conjugated polymers on the molecular packing and charge transport characteristics are thoroughly investigated and the optimal side-chain geometries for the most efficient charge transport are determined. Investigation of structure-property relationship in this work can provide new insight into the molecular design of high-performance polymer semiconductors.
