Beta-dione compounds with terminal vinyl group

Abstract

The invention discloses a beta-diketone compound with terminal alkenes, which has a structural formula (1) shown in the drawing, wherein the structure of R is shown in the drawing; and n is an integer from 3 to 10. The beta-diketone compound with terminal alkenes is a blue-violet light-emitting material, and can be used as a ligand for preparing an organic fluorescent complex, an organic phosphorescent complex, a rear earth complex and a polymer light-emitting material.

Description

technical field The present invention relates to a β-diketone compound, in particular to a terminal ene β-diketone compound. Background technique The application of β-diketone compounds in the fields of metal-organic liquid crystals, extraction reagents, chemical shift reagents, and anti-counterfeiting materials has attracted widespread attention. With unique photochemical properties, it can be widely used as functional materials such as photostability and photoetching. The tautomers of β-diketone compounds, because the hydrogen in the enol hydroxyl group has strong acidity, it is easy to be replaced by metals, and the carbonyl group can be used as an electron donor, so it can interact with most heavy metal ions and rare earth metals Ions form stable complexes, which are one of the most typical metal chelating agents, and are widely used in the synthesis of electroluminescent materials such as organic fluorescent complexes, organic phosphorescent complexes and rare earth c...
