Fluorinated amorphous polymeric gate-insulating materials for organic thin-film transistors (OTFTs) not only form hydrophobic surfaces but also significantly reduce traps at the interface between semiconductor and gate insulator. Therefore, these can enhance OTFT's operation stability. In this study, we synthesized a new insulating material series composed of acrylate fluorinated functional groups (with different ratios) named MBHCa-F used them as insulators OTFTs in other applications. The features polymers, including surface energy, atomic content properties, dielectric constant, leakage current, were clearly analyzed with respect to groups. At higher fluorine-based group content, exhibited contents superior electrical such field-effect mobility driving stability, OTFTs. believe that study provides substantial method synthesizing operational stability performance
