The spectroscopic behavior of ionic Eu3+ or Tb3+ complexes of an aromatic carboxyl-functionalized organic salt as well as those of the hybrid materials derived from adsorption of the ionic complexes on Laponite clay are reported. X-ray diffraction (XRD) patterns suggest that the complexes are mainly adsorbed on the outer surfaces of the Laponite disks rather than intercalated within the interlayer spaces. Photophysical data showed that the energy-transfer efficiency from the ligand to Eu3+ ions in the hybrid material is increased remarkably with respect to the corresponding ionic complex. The hybrid material containing the Eu3+ complex shows bright red emission from the prominent 5D0→ 7F2 transition of Eu3+ ions, and that containing the Tb3+ complex exhibits bright green emission due to the dominant 5D4→7F5 transition of Tb3+ ions.

A novel strategy for the asymmetric Michael addition of aldehydes to nitroolefins with a catalytic system of organocatalyst 1 in combination with ionic-liquid-supported (ILS) benzoic acid in water has been developed. The Michael adducts of this system giv
