Rectangular-plate like organosilica microcrystals based on silylated β-diketone and lanthanide ions†
Abstract
We report here the preparation of luminescent organosilica microcrystals with rectangular-plate morphology by a facile method of reacting silylated β-diketone with lanthanide ions under reflux without any structure-directing agent. Factors affecting the formation of the morphology including reaction temperature and the molar ratio of lanthanide/β-diketone are discussed.
