| 제목 | Organic semiconductor based on phenylethynyl end-capped anthracene for OTFT |
| 초록 | Organic thin film transistors (OTFTs) based on molecular and polymeric organic semiconductors have attracted considerable interest due to their lower cost deposition processes and higher compatibility with plastic substrates compared to silicon-based thin film transistors (TFT). In this study, a new molecular having anthracene core and phenylethynyl end groups is designed and synthesized. This molecular was expected to have deep highest occupied molecular orbital (HOMO) level, leading to higher stability than that of pentacene. Moreover, rigid rod structure with a high aspect ratio due to triple bond, leads to a higher long range ordering and a higher intermolecular π–π stacking compared to that of pentacene. Thus, the device incorporating this molecular shows a high charge mobility, stability and device reproducibility. |
