Mesoporous silicas have been obtained by the true liquid crystal templating (TLCT) method, using a surfactant Ru II complex as the template; on calcination, ruthenium-containing particles are deposited into the pores; the materials show high catalytic selectivity for the hydrogenation of hex-1-ene.

Lyotropic mesophases were observed for rare-earth trisdodecylsulphates, Ln(C 12 H 25 SO 4 ) 3 (Ln 5 Y, La, Ce-Lu, except Pm) in the presence of ethylene glycol or water (or mixtures thereof ) as the solvent. In ethylene glycol, a normal hexagonal phase and a cubic phase could be detected, whereas in water a normal hexagonal phase and a lamellar phase were found. Thus by changing the solvent, it is possible to obtain diOE erent supramolecular organizations within a series of lanthanide-containing metallomesogens.
