摘要：

Shape control: Gold nanorods are synthesized in high yields in the absence of shape-regulating agents in 1-ethyl-3-methylimidazolium ethylsulfate ([EMIM] [ES]). A two-step seeded-growth process is used that capitalizes on the binding affinity of imidazolium cations to gold crystal facets, the stabilization of AuI in [EMIM][ES], and the reduction of particle growth rates that is facilitated by weak reducing agents. © 2008 Wiley-VCH Verlag GmbH & Co.
