Disclosed are a light-emitting composite film, its manufacture method, and a white light organic electroluminescent device. Said light-emitting composite film comprises a first light-emitting layer and a second light-emitting layer. The first light-emitting layer comprises polyfluorene or polyfluorene derivatives, and the second light-emitting layer comprises quantum dots. A variety of color gamut and an improved brightness of devices can be achieved by the light-emitting composite film.

The present invention relates to compositions capable of emitting circularly polarized electroluminescence comprising an electroluminescent polymer and a chiral dopant, processes for the synthesis of such compositions and light emitting devices incorporating such compositions.

A resin particle includes a fluorescent colorant and a binder resin. The fluorescent colorant is bound to the binder resin by a chemical bond.

Provided are fire-fighting foam concentrate compositions incorporating multiple dye indicator agents, fire-fighting foams formed from said compositions, and to methods for evaluating fire-fighting foam concentrates. The compositions are useful as a complex anti-counterfeiting system and also allow for the differentiation of different types of authentic concentrates.

A quantum dot including a fluorine-containing ligand attached to a surface thereof and having a coating comprising a fluoropolymer over at least a portion of the outer surface of the quantum dot. A method for preparing a quantum dot with a coating comprising a fluoropolymer over at least a portion of the outer surface of the quantum dot is also disclosed. The method comprises contacting a quantum dot having a fluorine-containing ligand attached to a surface thereof with a fluoropolymer to coat the fluoropolymer over at least a portion of the outer surface of the quantum dot. A device including the quantum dot taught herein is further disclosed. An emissive material including the quantum dot taught herein is further disclosed.

Provided herein are phosphatidylethanolamine (PE)-specific probes and methods of use thereof. In particular, the present invention provides conjugates of PE binding moieties with detectable markers, and methods of use thereof to detect and/or characterize PE within cells.

Described herein are aqueous soluble polymersomes that encapsulate one or more hydrophobic fluorescent polymers and methods of their preparation and use.

Provided herein are functionalized pegylated cyanine compounds containing a reactive group suitable for labeling a biomolecule or pharmaceutical compositions and methods of use thereof. In one embodiment, the compounds are based on formula I shown below. ##STR00001##
In other embodiments, the compounds can be pegylated at one or more of the following locations R.sup.1, R.sup.4, R.sup.6, R.sup.9, or L.

Provided herein are phosphatidylethanolamine (PE)-specific probes and methods of use thereof. In particular, the present invention provides conjugates of PE binding moieties with detectable markers, and methods of use thereof to detect and/or characterize PE within cells.

A light-emitting marker particle having a light-emitting particle core containing a light-emitting material and first and second surface groups bound to the light-emitting particle core. The first surface group contains a polar group and is an inert group which does not bind to a biomolecule. The second surface group contains a biomolecule binding group.
