Effect of Alkyl Spacer Length on the Electrical Transport Properties of Diketopyrrolopyrrole-Based Polymer Semiconductors |
| 초록 |
A series of diketo-pyrrolopyrrole(DPP)-based polymer semiconductors with branched alkyl groups containing the linear spacer groups are synthesized to investigate the relationship between molecular structure and electrical properties. To date, however, despite the rapid process in the conjugated backbone and the side chain engineering, very little is known about the effect of odd and even numbers of carbon in the alkyl side chains on the molecular packing and electrical performance of conjugated polymers. Herein, odd-even effect of alkyl side-chain length in the 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 by systematic side-chain engineering. |
