Organic light emitting devices with host-guest bonding |
摘要 |
A compound having a host moiety chemically bonded to at least one guest moiety according to the following general molecular structure: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.
