一种新型的无机-有机纳米复合材料的组合被证明。蒽基树突，即，通过阴离子交换反应，将焦点上带有蒽发色团的聚酰胺-胺树枝状分子引入ZnAl-NO3型层状双氢氧化物（LDH）的层间.所得材料的光吸收和荧光性质与裸蒽基树枝分子不同。研究表明，这种光化学性质的变化是由于蒽发色团在LDH层间的有序化和π-π相互作用的结果。
A novel combination for an inorganic–organic nanocomposite material was demonstrated. Anthryl dendron, i.e., poly(amidoamine) dendron with an anthracene chromophore group at the focal point, was incorporated in the interlayer space of ZnAl–NO3type layered double hydroxide (LDH) through an anion-exchange reaction. The photoabsorption and fluorescence properties of the resulting material were different from those of the bare anthryl dendron molecule. It was suggested that the change in photochemical properties was due to the organization and π–π interaction of anthracene chromophores within the interlayer of the LDH.
