A Novel Functional Polyurethane as Dielectric Layer for Organic Thin-Film Transistors

Abstract

In this work, we design and synthesis a novel photosensitive polyurethane material as functional dielectric layer which can adjust the crystallization of para-hexaphenyl (p-6P). The novel polymer is synthesized with a new monomer 2,2-bis(hydroxymethyl)butyl 4-cyanobenzoate (HM-4-CB) that contain benzene to provide crystal nucleus. The grain size and density of p-6P crystal can be controlled by the content of HM-4-CB in the polymer structure. Therefore, this method can be used to regulate the grain size of semiconductor crystals and then to change the carrier mobility of the device. The result illustrates that with a suitable grain size of the p-6P semiconductor exhibit an excellent performance in terms of the charge carrier mobility.
