Controlled synthesis of asymmetrical gold nanokites was realized by reducing HAuCl4 with polyvinyl alcohol （PVA） in PVA-sodium dodecyl sulfate （SDS） aggregations aqueous solution at room temperature without any addi- tional reducing agents. The crystal structures, optical property and growth process of the gold nanokites were inves- tigated by X-ray diffraction （XRD）, Vis-NIR spectrum and transmission electron microscope （TEM）. HAuCl4 con- centration dramatically influenced the morphologies of the products. When HAuCl4 concentration was increased from 0.5 mmol·L^-1 to 2.2 mmol·L^-1, the products changed from network-like nanostructures to nanokites, nanoleaves and microplates. SDS was indispensable for the formation of gold nanokites and without SDS su- per-branched structures became the dominant products.
