Photographs of opaque emulsion and transparent solution of TMA-C2-DEA-C14 prepared by different methods. The opaque emulsion of TMA-C2-DEA-C14 was prepared by incubating in H2O for a month at room temperature. The transparent solution was dispersed in H2O by ultrasonication at a final concentration of 1.3 mM for 1.0 min.
