- Organic electroluminescent material and organic luminescent device thereof
-
The invention provides an organic electroluminescent material and an organic luminescent device thereof and belongs to the technical field of organic photoelectric materials. The organic electroluminescent material provided by the invention structurally contains a pyrene structure; and through connecting an aryl Si group, an aryl phosphine oxo group and an aryl sulfuryl group, a conjugate structure is effectively broken, and thus, a triplet energy level is higher. Meanwhile, the organic electroluminescent material provided by the invention structurally contains a powerful electron withdrawinggroup, so that the organic electroluminescent material has excellent electron transporting capability, can be applied to the organic luminescent device as a luminescent layer material or electron transport layer material and has higher luminescence efficiency and lower driving voltage.

- PHOSPHINE COMPOUND, PROCESS FOR PRODUCING THE SAME, AND PEROXIDE SCAVENGER USING THE SAME
-
The invention provides a novel peroxide scavenger comprising a phosphine compound represented by general formula [I]: wherein Z1 and Z2 each represents a cyclic group; Ar represents an arylene group; R represents an aliphatic hydrocarbon group; Y represents phosphorus (P), nitrogen (N), or bismuth (Bi); and R1, R2, and R3 each represents a cyclic group, particularly a peroxide scavenger that can scavenge peroxides such as reactive oxygen species which are generated in mitochondria upon exposure to oxidative stress and localized in mitochondria. The phosphine compound of the invention is oxidized by the peroxides localized in mitochondria to increase the fluorescence intensity, whereby the peroxides can be scavenged.
