Investigation of Structure-Property Relationships in Diketopyrrolopyrrole (DPP)-Based Polymer Semiconductors |
| 초록 |
Side-chain engineering via tuning of the alkyl-chain branching point has been proven to boost electrical performance in conjugated polymers. 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 alkyl side chains on the molecular packing and electrical performance of conjugated polymers. 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 by systematic side-chain engineering. Investigation of structure-property relationship in this work can provide new insight into the molecular design of high-performance polymer semiconductors. |
