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.

Abstract: The present teachings relate to compositions for forming a negative-tone photopatternable dielectric material, where the compositions include, among other components, an organic filler and one or more photoactive compounds, and where the presence of the organic filler enables the effective removal of such photoactive compounds (after curing, and during or after the development step) which, if allowed to remain in the photopatterned dielectric material, would lead to deleterious effects on its dielectric properties.

Abstract: Disclosed are polymer-based dielectric compositions (e.g., formulations) and materials (e.g. films) and associated devices. The polymers generally include photocrosslinkable pendant groups; for example, the polymers can include one or more coumarin-containing pendant groups.

Abstract: The present teachings relate to organic semiconductor formulations including an organic semiconducting compound in a liquid medium, where the liquid medium includes (1) a compound in liquid state that has electronic properties complementary to the electronic structure of the organic semiconducting compound and optionally (2) a solvent or solvent mixture for solubilizing the organic semiconducting compound. The present formulations can be used as inks in the fabrication of organic semiconductor devices.
