Mesoporous hybrids containing Eu{sup 3+} complexes covalently bonded to SBA-15 functionalized: Assembly, characterization and photoluminescence
- Department of Chemistry, Tongji University, Siping Road 1239, Shanghai 200092 (China)
A novel series of luminescent mesoporous organic-inorganic hybrid materials has been prepared by linking Eu{sup 3+} complexes to the functionalized ordered mesoporous SBA-15 which was synthesis by a co-condensation process of 1,3-diphenyl-1,3-propanepione (DBM) modified by the coupling agent 3-(triethoxysilyl)-propyl isocyanate (TEPIC), tetraethoxysilane (TEOS), Pluronic P123 surfactant as a template. It was demonstrated that the efficient intramolecular energy transfer in the mesoporous material Eu(DBMSi-SBA-15){sub 3}phen mainly occurred between the modified DBM (named as DBM-Si) and the central Eu{sup 3+} ion. So the Eu(DBMSi-SBA-15){sub 3}phen showed characteristic emission of Eu{sup 3+} ion under UV irradiation with higher luminescence quantum efficiency. Moreover, the mesoporous hybrid materials exhibited excellent thermal stability as the lanthanide complex was covalently bonded to the mesoporous matrix. - Graphical abstract: A novel organic-inorganic mesoporous luminescent hybrid materials is prepared by linking the binary and ternary Eu{sup 3+} complexes to the functionalized ordered mesoporous SBA-15 with the modified 1,3-diphenyl-1,3-propanepione (DBM) via a co-condensation process of tetraethoxysilane (TEOS) in the presence of Pluronic P123 surfactant as a template.
