Improving Bulk Electron Transportation of Low-Crystalline NDI-based n-Type Conducting Polymer with Localized Aggregates via Kinetically Fast and Robust Interactions |
| 초록 |
Naphthalene diimide (NDI)-based polymers used as a n-type material are widely used in organic electronic devices. Most NDI-based polymers have large crystal domains due to self-assembling process of NDI, which limits an efficient electron transportation in amorphous region. Increase in interconnectivity between polymer chains can provide effective approach to improve electron mobility in amorphous region and lower the activation energy in charge transportation. In this respect, we designed and synthesized the copolymer of NDI and fluorinated dithienylethene (FTVT) unit (PNDI-FTVT). FTVT unit which has strong dipole moment formed localized aggregates via kinetically fast and robust intermolecular interactions. These aggregates hinder self-assembling process of NDI as well as increase interconnectivity between polymer chains in amorphous region, resulting in one order higher the bulk electron mobility compared to PNDI-TVT. |
