Findings from Tongji University Yields New Data on Microporous and Mesoporous Materials [Multi-component hybrids of surfactant functionalized europium tetrakis (beta-diketonate) in MCM-41(m) and polymer modified ZnO for luminescence integration]

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Microporous and Mesoporous Materials are presented in a new report. According to news reporting originating from Shanghai, People's Republic of China, by NewsRx correspondents, research stated, "Surfactant dodecyl(11-(methacryloyloxy)undecyl)dimethylammonium bromide (DMDA) is utilized as the chemical linkage to assemble multi-component photofunctional hybrids. Europium (III) tetrakis (beta-diketonate) complexes (beta-diketonate (L) = 2-thenoyltrifluoroacetonate (TTA), 4,4,4-trifluoro-1-phenyl-1,3-butanedionate (BTA), trifluoroacetylacetonate (TAA)) are connected with DMDA via anion exchange reaction to form Eu(L)(4)DMDA."

Our news editors obtained a quote from the research from Tongji University, "Then Eu(TTA)(4)DMDA system is encapsulated into (3-aminopropyl)triethoxysilane functionalized MCM-41 host, resulting in MCM-41(m)-Eu(L)(4)DMDA assembly. At the same time, methacrylic-group-modified ZnO nanoparticles (designated ZnO-MAA) are prepared through sol-gel reaction between zinc methacrylate and LiOH. Finally ZnO-MAA and MCM-41(m)-Eu(L)(4)DMDA are covalently bonded together with copolymerization reaction between MAA and DMDA units at the presence of benzoyl peroxide (BPO). The detailed physical characterization and especially the photoluminescence of these hybrid materials are studied in detail. Besides the uniformity is kept in the mesostructure, the characteristic emission of both Eu3+ complex system and modified ZnO unit are obtained. It is interesting that the white luminescence is obtained for MCM-41(m)-Eu(TAA)(4)DMDA-ZnO by the emission integration of ZnO unit and Eu3+."

According to the news editors, the research concluded: "The results provide a strategy to assemble multi-component hybrids in mesoporous host."
