Influence of fluorination on the charge transport property and air stability |
| 초록 |
Incorporating Fluorine (F) atom into polymer backbones can not only lower the highest occupied molecular orbital (HOMO)/ lowest unoccupied molecular orbital (LUMO) levels but also prompt denser packing through non-covelant interactions. In this study, by introducing different ratios of F into a n-type copolymer P(NDIOD-T2) consisting of NDI and 2,2'-thiophene (T2), the influence of fluorination on the charge transport property and air stability was investigated. It was discovered that as the ratio of F increased, the size of the crystallites decreased, affected by less-oriented crystalline structure. However, P(NDIOD-T2F100) exhibit superior operational stability under wet conditions and does not show any negative change in the electrical properties after immersion in water for 30 min. This allows us to understand the change in the morpholgy/crystallinity, device performance, and device stability of n-type copolymers as a function of F content. |
