Intercalation and formation of three fluorescent complexes, Al(III)-, Cr(III)- and Cu(II)-10-hydroxybenzo[h]quinolone (M-HBQ, M = Al, Cr and Cu), in the interlayer spaces of magadiite (mag) were studied by solid-solid reactions between metal ions exchanged mags (M-mag, M = Al, Cr and Cu) and HBQ. Results show that the basal spacings of the intercalated composites increase after the intercalation of HBQ into M-mags. The amount of HBQ in the intercalated compounds is different due to the amount of metal ions and the diversification of coordination ability of metal ions, and the order of the coordination ability of these three metal ions is Cu > Cr > Al. The amount of the metal cations in the interlayer of mag is enough for the complex formation of M-HBQ complexes. The slight shift of the absorption and luminescence bands of the complexes suggests the different microstructures, including molecular packing of the complexes in the interlayer spaces of mags, resulting that the host-guest interactions are formed. These findings show that the intercalation and formation of M-HBQ complexes (M = Al, Cr and Cu) in the interlayer space of mag are successfully achieved in the current work.
通过金属离子交换的片钠铝石（M-片钠铝石，M = Al、Cr和Cu）与10-羟基苯并[h]喹啉（HBQ）之间的固-固反应，研究了Al(III)-、Cr(III)-和Cu(II)-10-羟基苯并[h]喹啉（M-HBQ，M = Al、Cr和Cu）三种荧光配合物在片钠铝石（mag）层间空间的插层和形成情况。结果表明，将HBQ插入M-片钠铝石后，插层复合材料的基面间距增加。由于金属离子的量以及金属离子配位能力的差异，插层化合物中HBQ的量有所不同，这三种金属离子的配位能力顺序为Cu＞Cr＞Al。片钠铝石层间的金属阳离子量足以形成M-HBQ配合物。配合物吸收和发光带的轻微移动表明其微观结构不同，包括配合物在片钠铝石层间空间的分子堆积情况，从而形成了主客体相互作用。这些发现表明，在当前工作中成功实现了M-HBQ配合物（M = Al、Cr和Cu）在片钠铝石层间空间的插层和形成。
