  Self-assembled dendronized CdS nanoparticles have been attracting
considerable attention because of their photoluminescence properties depending
on annealing treatments. In this study, their annealing-induced self-assembled
structure was investigated via scanning transmission electron microscopy
(STEM); thin foil specimens of self-assembled dendronized CdS nanoparticles
were prepared by ultramicrotomy and the STEM images revealed their ordered
structure and the effect of the annealing treatment. In addition, a structural
order belonging to the P213 space group was identified via an autocorrelation
analysis. The results indicated that this structural order could be achieved
only over a few tens of nanometers.
