The interfaces between [C₁₂mim][NTf₂], an ionic liquid containing long-chain alkyl groups, and various substrates were investigated by FM-AFM using a qPlus sensor. Topographic images were obtained at the [C₁₂mim][NTf₂]/KCl{100} interface and the [C₁₂mim][NTf₂]/HOPG interface. Atomic resolution imaging of the KCl{100} surface was successfully achieved. On HOPG, a stripe-like structure resembling the alkane/HOPG interface structure was observed.
