摘要:
Spiro-type conjugated polymers having the following general formula 1 wherein XnullC or N; R1-R16 is independently selected from H, D, alkyl, alkoxyl, silyl, aromatic ring, fused aromatic ring, heteroaromatic ring, fused heteroaromatic ring, diarylamino group, carbazole, and at least one of them being a crosslinkable group consisting of a vinyl double bond or an azide group are useful in the fabrication of organic light emitting devices.
摘要:
Organic semiconductors consisting of conjugated chromophores wherein one or more hydrogen atoms are deuterated are disclosed. Methods of preparing such organic semiconductors are described. The organic semiconducting compounds exhibit remarkably high luminescence and good thermal stability. Applications of these materials for optoelectronic devices, such as light-emitting devices and photodiodes, with enhanced performance and lifetime are disclosed. The disclosed materials can be used as emissive layer, charge-transporting layer, or energy transfer (i.e. phosphorescence dopant) material in organic light-emitting devices.
摘要:
A compound having a host moiety chemically bonded to at least one guest moiety according to the following general molecular structure: Ho-(L-G)n. Ho represents a host moiety that receives hole and/or electron recombination energy and transfers that energy to a guest moiety; G represents a guest moiety that contains a luminescent chromophore; L represents a chemical moiety that links the host and guest moiety and n is from 1 to 4. The compound can be used in the emissive layer of an OLED, or as a dopant dispersed in a host material that forms the emissive layer, wherein the host material has the same chemical structure as Ho.

摘要:
An organic light emitting device (OLED) in which an anode includes a gold or gold composition layer under a thin layer of thiol or thiol-derivative. Preferably, the thin layer of thiol or thiol derivative is a self-assembled monolayer so as to enhance interface properties with other layers (such as a hole transporting layer) in the OLED.
