Abstract: The present teachings relate to curable linear polymers that can be used as active and/or passive organic materials in various electronic, optical, and optoelectronic devices. In some embodiments, the device can include an organic semiconductor layer and a dielectric layer prepared from such curable linear polymers. In some embodiments, the device can include a passivation layer prepared from the linear polymers described herein. The present linear polymers can be solution-processed, then cured thermally (particularly, at relatively low temperatures) and/or photochemically into various thin film materials with desirable properties.

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.
