Patent ID: 8911883

Claim:
An organic-inorganic hybrid electroluminescent device comprising: a semiconductor nanocrystal pattern prepared by coating a substrate with a dispersion in an organic solvent of semiconductor nanocrystals, wherein the semiconductor nanocrystals are surface-coordinated with a compound containing photosensitive functional groups; evaporating the organic solvent to form a film of the surface-coordinated semiconductor nanocrystals on the substrate; exposing the film to light through a mask; cross-linking the photosensitive functional groups to form a network structure of the semiconductor nanocrystals; and developing the exposed film, wherein the compound containing a photosensitive functional group is represented by Formula 1 below: X-A-B (1), wherein X is NC—, HOOC—, HRN—, POOOH—, RS— or RSS—, in which R is a hydrogen atom or a C 1˜10 saturated or unsaturated aliphatic hydrocarbon group; A is a direct bond, a saturated aliphatic hydrocarbon group, a phenylene group, a biphenylene group, an aliphatic ester group, an aliphatic amide group, an aliphatic oxycarbonyl group or an aliphatic ether group; and B is an organic group containing at least one carbon-carbon double bond, which may be substituted with at least one group selected from the group consisting of —CN, —COOH, halogen groups, C 1˜5 halogenated alkyl groups, amine groups, C 6˜15 aromatic hydrocarbon groups, and C 6˜12 aromatic hydrocarbon groups substituted with F, Cl, Br, a halogenated alkyl group, R′O—, in which R′ is a hydrogen atom or a C 1˜5 alkyl group, —COOH, an amine group, or —NO 2 .
