SUMMARY
To overcome this issue, flexible side chains such as alkyl, fluoroalkyl, and oligo(ethylene glycol) chains are appended to pi-conjugated backbones to enhance solubility, facilitate solution processing, and tune intermolecular packing3,4. In recent years, side chain engineering has been pursued organic electronic materials, which highlights the importance of side chain length, bulkiness, branching, substitution, and chain-end functionalization on charge transport in conjugated polymers3,4. Despite recent progress, the role of side chain chemistry on the molecular charge transport properties of conjugated organics is not fully understood. The results show that molecular . . .
