Molecules That Assemble by Sound: An Application to the Instant Gelation of Stable Organic Fluids

摘要

Stimuli-responsive aggregations of low molecular weight materials have been intensively studied in gels,micelles,vesicles,and synthetic membranes,with the aim of creating future technologies for the control of fluidity,viscoelasticity,solvent volatility,optical transmission,ion transport,etc.Light and electrochemical controls have been explored as a means of switching molecular aggregations without the use of chemical stimuli.However,providing a method of control that is instant,positive (i.e.,converting sol to aggregate),and reversible,while also being versatile and practical,remains a challenge.
