Abstract
Official abstract text for this publication.
Synthesis of platinum(II) di(2-pyrazolyl)benzene chloride and analogs includes forming a 1,3-di-substituted benzene including two aromatic five-membered heterocycles, and reacting the 1,3-di-substituted benzene with an acidic platinum-containing solution to form a luminescent platinum(II) complex. The luminescent platinum(II) complex is capable of emitting blue and white light and can be used as an emitter in a light emitting device.
First claim
Opening claim text (preview).
What is claimed is: 1. A luminescent compound comprising: wherein is an imidazole ring, each X is a nitrogen atom, and W is —Cl or 2. The compound of claim 1 , wherein each Z is a nitrogen atom. 3. The compound of claim 2 , wherein each Z has a methyl substituent. 4. The compound of claim 1 , wherein the benzene ring is fluorinated, difluorinated, or methylated. 5. The compound of claim 1 , wherein the compound is phosphorescent. 6. The compound of claim 1 , wherein the compound emits light in the blue range of the visible spectrum. 7. The compound of claim 1 , wherein the compound emits white light. 8. A light emitting device comprising a luminescent compound comprising: wherein is an imidazole ring, each X is a nitrogen atom, and W is —Cl or 9. The light emitting device of claim 8 , wherein each Z is a nitrogen atom. 10. The light emitting device of claim 9 , wherein each Z has a methyl substituent. 11. The light emitting device of claim 8 , wherein the benzene ring is fluorinated, difluorinated, or methylated. 12. The light emitting device of claim 8 , wherein the compound is phosphorescent. 13. The light emitting device of claim 8 , wherein the compound emits light in the blue range of the visible spectrum. 14. The light emitting device of claim 8 , wherein the compound emits white light. 15. The light emitting device of claim 8 , wherein the device is an organic light emitting device.
