Four-toothed cyclometalated platinum complex with three-substituted pyrazole and preparation method and application
-
Paragraph 0138; 0139; 0140, (2019/08/12)
The invention relates to the field of blue light phosphorescence four-toothed cyclometalated platinum complex light emitting materials and discloses a blue light phosphorescence four-toothed cyclometalated platinum complex with three-substituted pyrazole and a preparation method and application. The complex can be a delayed fluorescence and/or phosphorescence emitter, has the characteristics of high thermal decomposition temperatures, great quantum effects, blue light emission, relatively narrow light emission spectrums, and the like, and thus has great application prospects in the field of blue light, particularly dark blue light phosphorescence materials.

experimental part, p. 756 - 761 (2011/08/06)
Factors determining the reaction of metal β-diketonates with hydrazine, in particular the nature of central metal ion and structure of β-diketonate ligand, are discussed. The possibility for the preparation of other heterocyclic compounds via reaction of metal acetylacetonates with phenylhydrazine, o-phenylenediamine, urea, and thiourea was studied.
