Abstract: The present teachings relate to an organic electroluminescent transistor with improved light-emission characteristics. More specifically, the present organic electroluminescent transistor has an emissive ambipolar channel including at least one layer of an n-type semiconductor material, at least one layer of a p-type semiconductor material, and at least one layer of an emissive material arranged between the layers of the p-type and n-type semiconductor materials, where the multilayer emissive ambipolar channel includes, among various layers, a layer of a p-type semiconductor material comprising a benzothieno-benzothiophene compound, and/or a layer of an emissive material comprising a blend material that includes an organic carbazole derivative as the host matrix compound and an iridium complex as the guest emitter.

Abstract: The present teachings relate to a photopatternable composition including a vinylidene fluoride-based polymer, a photosensitive non-nucleophilic base, and a crosslinking agent. The photopatternable composition can be used to prepare a patterned thin film component for use in an electronic, optical, or optoelectronic device such as an organic thin film transistor. The patterned thin film component can be used as a gate dielectric with a high dielectric constant, for example, a dielectric constant greater than 10.
