Solution-processed hydroxyl containing polymers like poly(4-vinylphenol) are widely utilized in organic filed-effect transistors (OFETs) due to their high dielectric constant (k) and excellent insulating properties by crosslinking thourgh hydroxl groups. However, hydroxyl functionalities can activate as trapsites, and crosslinking reactions of these materials decrease the k values. Accordingly, we try to maintain the merits while compensating for the disadvantages of these materials by synthesizing a new solution-processable copolymer containing hydroxyl and hydrophobic functionalities together. Also, we add fluorophenyl azide (FPA) based UV-assisted crosslinker to yield crosslinking. |
