Novel photofunctional hybrid materials (alumina and titania) functionalized with both MOF and lanthanide complexes through coordination bonds

摘要: In this paper, series of luminescent hybrid materials (alumina, titania) functionalized with both lanthanide complexes and metal organic frameworks (MOF, Al-MIL-53-COOH) through coordination bonds. these systems, MOF (Eu3+, Tb3+) beta-diketonates (2-thenoyltrifluoroacetonate (TTA), 1,1,1-trifluoroacetylacetone (TAA), 2,4-pentanedionate (AA)) pyridine-3,5-dicarboxylic acid (PDA) are coordinated to alumina titania their carboxylic groups. Al-MIL-53-COOH possesses the active –COOH group can be linked metallic alkoxides (Ti[OCH(CH3)2]4 Al[OCH(CH3)2]3), by a post-synthesis path. Ternary PDA further bonded as bridge for its coordination. After hydrolysis condensation process, final multi-component assembled characterized. The photophysical properties were studied in detail, color tuned controlling composition different units system. Especially hybrids europium MOF, white luminescence obtained integrating emission complex MOF. Furthermore, films that prepared show uniformity transparency. These results provide some useful data assembly integration photofunctional based on units, which expected have potential applications devices display or lighting.
