The molecular linkage (phenSi) is modified from 5-amino-1,10-phenanthroline (phenNH(2)) by 3-(triethoxysilyl)-propyl isocyanate (TESPIC). Then phenNH(2) functionalized periodic mesoporous organosilica (PMO) hybrids are synthesized by linking ternary europium complexes with phenSi linkage and 2-methyl-9-hydroxyphenalenone (MHPO), which use co-condensation method in the presence of Pluronic P123 surfactant as a template. The europium PMO hybrid system (denoted as Eu(MHPO)(3)phen-PMO(NO3)(3)) has been characterized in detail, whose results reveal that these hybrids have uniformity in the mesopore structure. It is worthy pointing out that the europium hybrids show emission of both europium ion and phen functionalized PMOs, which can be integrated into the close white luminescence. This provides us a strategy to obtain white emissive lanthanide hybrids.(c) 2013 Elsevier B.V. All rights reserved.
