Near infrared strongly luminescent rare earth complexes

摘要

Closely you could do this invention, in order to offer the infrared it possesses the luminous quality which is superior closely in the infrared territory strongly luminous characteristic rare earth complex. This invention infrared as for the luminous characteristic rare earth complex, the structure general formula below (1) (in formula, as for Ln (iii) shows the rare earth ion of 3 value closely strongly. n shows the integer of 3 or more, X equality or the hydrogen atom, the deuterium atom and the halogen atom which differ, the basis of C₂₀, hydroxyl group, the nitro group, the amino group, the sulfonyl basis, the cyano basis and the shiriru basis, phosphon acid radical, shows either the diazo basis or the merukaputo basis from C₁ Z shows the ligand of two seats.)So it features that it is displayed.
