We investigated oscillatory motion of a camphor disk floating on water containing 5 mM hexylethylenediaminium trifluoroacetate (HHexen-TFA) as an ionic liquid (IL). The frequency the increased with increasing concentrations transition metal ions Cu2+ and Ni2+ but was insensitive to Na+, Ca2+, Mg2+, typical in phase. surface tension phase HHexen-TFA also Mg2+. Based density functional theory, metal-ion species-dependent response is discussed regard force self-propulsion complex formation between ions. These results suggest that (Cu2+, Ni2+) ethylenediamine group IL increases around disk, resulting increase or Ni2+. present study suggests nature can be created by complexation, which changes self-propulsion.
