Grafting luminescent metal-organic species into mesoporous MCM-41 silica from europium(III) tetramethylheptanedionate, Eu(thd) 3
Mixed systems with Eu(III) β-diketonates as optically active guest species, and mesoporous silicas MCM-41 as a host matrix have been investigated. The grafting of europium(III) onto the inner walls of unmodified MCM-41 has been achieved starting from Eu(thd) 3 (thd = 2,2,6,6-tetramethyl-3,5-heptaned...
