RESUMO
Controlling phase separation and transition plays a core role in establishing and maintaining the function of diverse self-assembled systems. However, it remains challenging to achieve wide-range continuous phase transition for dynamically producing a variety of assembled structures. Here, we developed a far-from-equilibrium system, upon the integration of photoexcitation-induced aggregation molecules and block copolymers, to establish an in situ phase-volume ratio photocontrol strategy. Thus, full-scale phase-diagram structures, from lamellar structure to gyroidal, cylindrical, and finally to a spherical one, can be accessed under different irradiation periods. Moreover, the phase transition was accompanied by considerable aggregation-induced phosphorescence and hydrophilicity/hydrophobicity change for building a functional surface. This strategy allows for a conceptual advance of accessing a wide range of distinct self-assembled structures and functions in real time.
