Different Self-Assembly Behavior of Amphiphilic Molecules under Diverse Precipitating Conditions

We present investigations on the microcosmic self-assembly process of new synthesized amphiphilic DMAPNPP molecules. During the temperature decrease and solvent evaporation of the amphiphilic molecules' saturated solution, the amphiphilic molecules first assembled into thinner belt-like arms extending from a core. And then the curled belts not only served as the directing template but also were straightened during the subsequent assembly process. This conclusion well illuminates why the dimensions can be controlled by adjusting the amphiphilic molecules' deposition temperature and rate from their saturated solution. It opens a new avenue for conveniently adjusting the self-assembly dimension of similar amphiphilic molecules.
