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.

Organic semiconductor formulations

The present polymeric materials can be patterned with relatively low photo-exposure energies and are thermally stable, mechanically robust, resist water penetration, and show good adhesion to metal oxides, metals, metal alloys, as well as organic materials. In addition, these polymeric materials can be solution-processed (e.g., by spin-coating), and can exhibit good chemical (e.g., solvent and etchant) resistance in the cured form.

Photopatternable materials and related electronic devices and methods

Described herein is a solution-processable composition for preparing a photopatternable material. The solution-processable composition generally includes (a) an oligomeric siloxane component that includes, based on its total weight, between about 40% by weight and about 100% by weight one or more cage-structured polyhedral oligomeric silsesquioxanes that are functionalized with one or more crosslinkable moieties such as cycloaliphatic epoxy moieties, (b) a polymerization initiator; (c) one or more thermosettable polymers that collectively are present in an amount between about 1% by weight and about 20% by weight based on the total weight of the oligomeric siloxane component; and (d) a solvent.

Disclosed are 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.

Disclosed are new compounds having semiconducting properties. Such compounds can be processed into thin film semiconductors that exhibit high carrier mobility and/or good current modulation characteristics.

Compounds having semiconducting properties and related compositions and devices

Disclosed are polysulfone-based materials that can be used as active and/or passive components in various electronic, optical, and optoelectronic devices, particularly, metal-oxide-semiconductor field-effect transistors. For example, various metal-oxide-semiconductor field-effect transistors can include a dielectric layer and/or a passivation layer prepared from such polysulfone-based materials and exhibit good device performance.

Polymeric materials for use in metal-oxide-semiconductor field-effect transistors

Disclosed are molecular and polymeric compounds having desirable properties as semiconducting materials. Such compounds can exhibit desirable electronic properties and possess processing advantages including solution-processability and/or good stability.
