Abstract

Layered dendrimer-loaded zinc arsenates (ZnAs) were synthesized under hydrothermal conditions. The so-called DAB-Am-n family of dendrimers is used to produce ZnAs solids with variable interlayer distances. Analysis of the 00k X-ray diffraction reflections reveals that the higher-generation DAB-Am-n dendrimers are "squeezed" between the ZnAs layers, judging from the observation of interlayer spacings that increase more slowly with dendrimer generation than the actual average diameters of the free dendrimers. Transmission electron microscopy shows that, under the synthetic conditions adopted here, the ZnAs sheets are subject to some level of bending and defects. The temperature-programmed oxidation patterns and elemental analysis of these materials are also discussed.
