Title:
RARE EARTH METAL COMPLEX
Document Type and Number:
WIPO Patent Application WO/2012/070420
Kind Code:
A1
Abstract:
A rare earth metal complex comprising a rare earth metal atom and a β-diketone compound which is represented by formula (1) and is coordinated to the rare earth metal atom. In formula (1), R1 represents a hydrogen atom, a halogen atom, an alkyl group, a perfluoroalkyl group, an alkoxy group, a perfluoroalkoxy group, a nitro group, an amino group, a sulfonyl group, a cyano group, a silyl group, a phosphone group, a diazo group, a mercapto group, an aryl group, an aralkyl group, an aryloxy group, an aryloxycarbonyl group, an allyl group, an acyl group, or an acyloxy group.
