Disclosed are a composition including a silane-based organic/inorganic hybrid material having a multiple bond and one or more organic metal compounds and/or one or more organic polymers, an organic insulator including the composition, an organic thin film transistor (OTFT) including the organic insulator and an electronic device including the OTFT. The organic insulator including the composition for preparing an organic insulator has increased charge mobility and an increased on/off current ratio, thus exhibiting improved properties, and the organic thin film transistor manifests uniform properties due to the absence of hysteresis.

Composition and organic insulator prepared using the same

Disclosed is a composition for preparing an organic insulator, including an organic silane material, having a vinyl group, an acetylene group or an acryl group as a functional group for participating in a crosslinking reaction, a crosslinking agent, and a solvent for dissolving the above components. The organic insulator of example embodiments may be provided in the form of a solid insulating film, which may increase charge mobility while decreasing the threshold voltage and operating voltage of OTFTs, and which also may generate relatively slight hysteresis.
