报道了一种在纳米L型沸石材料上接枝铽有机配合物的方法。采用3-氨丙基三乙氧基硅烷对L型分子筛进行功能化，然后通过L型分子筛表面的氨基与异硫氰酸酯基团反应，接枝羧基苯异硫氰酸酯，制备了有机-无机杂化材料。最后将功能化的L型分子筛与铽（111）离子反应。通过红外光谱、荧光光谱和扫描电镜等手段对所得有机-无机杂化材料进行了详细的表征。通过荧光光谱和红外光谱证实了稀土配合物在纳米L沸石上的接枝。(c)2008年爱思唯尔B。V.保留所有权利。
A procedure for the grafting of terbium organic complexes onto nanozeolite L material is reported. The organic-inorganic hybrid material was prepared by first functionalizing zeolite L with (3-aminopropyl) triethoxysilane and then grafting carboxyphenyl isothiocyanate via the reaction of amino group covered on zeolite L surface and isothiocyanate groups. The functionalized zeolite L was at last reacted with terbium (111) ions. The obtained organic-inorganic hybrid materials were detailed investigated by means of FT-IR, luminescence spectroscopy and SEM techniques. The grafting of lanthanide complexes onto nanozeolite L was confirmed by the luminescence spectra and FT-IR spectra. (c) 2008 Elsevier B. V. All rights reserved.
