The present invention provides a cover layer molecular structure. The cover layer molecular structure includes a macromolecular structure formed by bonding a first central structure to a second central structure. The first central structure is one of 9,9-dimethyl-2-bromofluorene, 2-bromo-9,9-spirobifluorene, and 2-bromo-9,9-diphenylfluorene. The second central structure is either of 3-p-tolyl-4-m-tolyl-diphenylamine and 4,4-bis(3,5-xylyl)-diphenylamine.

A light-emitting device includes an emissive layer in which first and second charge carriers recombine to emit light; a first electrode from which the first charge carriers are generated and a second electrode from which the second charge carriers are generated; a first charge transport layer that injects the first charge carriers from the first electrode into the emissive layer; and a second charge transport layer that injects the second charge carriers from the second electrode into the emissive layer. The emissive layer includes quantum dots having a core in which the first and second charge carriers recombine and a shell, and at least a portion of the quantum dots have a Quasi-Type II configuration in which the first charge carriers are confined to the core and the second charge carriers are non-confined charge carriers that are not confined to the core or the shell. The confined charge carriers may be the electrons and the non-confined charge carriers may be the holes, or vice versa.

A film-forming composition for ink-jet coating which comprises: a triazine-ring-containing polymer including, for example, the repeating unit structure represented by the following formula [3]; and an organic solvent comprising more than 50 mass % solvent based on a glycol dialkyl ether. The composition is less apt to corrode the heads of ink-jet coating devices, and droplets thereof are satisfactorily ejected in ink-jet coating. Therefore, with the composition, it is possible to easily produce a high-refractive-index film according to a desired pattern through pattern printing by an ink-jet coating device. ##STR00001##

This invention relates to polymer-based partially-open, hollow reservoirs in the nano-size to micro-size range that encapsulate an additive, which can be released from the reservoirs using specific event stimuli such as reduction-oxidation and voltage change, or at will, using the same stimuli. This invention also relates to method preparing such reservoirs, and for releasing the additive. This invention further relates to matrix that comprises such reservoirs and the method of preparing such matrix. This invention also relates to applications, for example in corrosion inhibition, lubrication, and adhesion, that benefit from using such a controlled release of an additive.
