There were obtained 1.88 parts of an optically active rare earth complex (S-II complex; hereafter referred to as S-II rare earth complex (17)).
- S-II complex optically active rare earth complex
- S— S rare earth complex (18) An optically active rare earth complex represented by (18) (S— ⁇ isomer; hereinafter, referred to as S— S rare earth complex (18)) was obtained.
- the S— ⁇ rare-earth complex (7) and the S— ⁇ rare-earth complex (9) of the present invention and a comparative compound Three solutions were prepared by dissolving 1 part of each in 5 parts of acetone. This solution was irradiated with ultraviolet light (about 365 nm) by a black light lamp. The solutions of the S—— rare earth complex (7) and the S— (rare earth complex (9) of the present invention emitted strong red light. Only very weak luminescence was observed.
- FIG. 1 shows the emission intensity when excited at a wavelength of 410 nm.
- the optically active rare earth complex of the present invention and a comparative compound a large difference in emission intensity was observed between tris (3-trifluoroacetyl camphorato) and pium in the mouth.
- the S— ⁇ rare earth complex (13) of the present invention and the comparative compound: S— ⁇ rare earth complex (18) were prepared, and 0.1 part of each was dissolved in 5 parts of acetone. Two solutions were prepared. Since each of the complexes emits light in a wavelength region of 900 nm or more (infrared region), the fluorescence emission of the solution is performed using a SPEX Fluo 01 og-3 system corresponding to the measurement in the wavelength region. The strength was compared.
- FIG. 2 shows the emission intensity when excited at a wavelength at which the excitation spectrum is maximized (S— ⁇ rare earth complex (13) of the present invention: 405 nm, S— ⁇ rare earth complex (18): 366 nm).
- the optically active rare earth complex of the present invention had a higher luminous intensity than the comparative compound: S- ⁇ rare earth complex (18).
- an optically active rare earth complex having a very large emission intensity and a circularly polarized light emission, as compared with a conventional optically active rare earth complex having a circularly polarized light emission.
- the optically active rare earth complex having circularly polarized light emission of the present invention has high color purity and high light emission Since it has a very high intensity and can effectively use emitted light, it is suitably used for luminescent inks and organic electroluminescent devices.
