AB - A potential gate dielectric material that can be cured and processed at low temperatures was designed and synthesized via the cross-linking of bisphenol A novolac (Novolac) and hexamethoxymethylmelamine (HMMM) in the presence of a catalytic amount of p-toluenesulfonic acid. The thin films of the prepared insulator, Novolac-MM, were completely solidified after cross-linking at 100 °C. Metal–insulator–metal (MIM) devices and pentacene-based p-type organic thin-film transistors (OTFTs) using the synthesized polymer as a dielectric layer were fabricated and compared to poly(vinylphenol)-based materials. Novolac-MM devices showed low leakage current (<10−8 A cm−2) and higher hole mobility (0.31 cm2 V−1 s−1) than PVP devices (0.23 cm2 V−1 s−1). Flexible OTFTs using Novolac-MM were also fabricated, and were found to be processable at low temperatures.
