Abstract Understanding the complexity of nanostructures involved during supramolecular polymerization process can be achieved by kinetic control rather than thermodynamic stability. Study on pathway and associated will provide precise over materials' properties. This work illustrates structural transformation a naphthalimide‐(NMI)‐conjugated dipeptide from monomer to thermodynamically stable aggregated state in binary mixed solvent system (DMSO water). The self‐assembly propensity modulated changing ratio water, which offers an effective approach stability on‐pathway gel before reaching its crystalline precipitate state. An in‐depth spectroscopic microscopic investigation suggested that initiated formation tiny particles, further nucleated form helical nanofibrilar assembly. At higher water percentages, showed transient behavior proceeded toward However, at lower percentage, is kinetically trapped Here, helicity nanofibers altering percentage solvent. self‐assembled completely thermoreversible retain chiral memory even after complete dissolution respective composition.
