Chemically Fueled Autonomous Sol→Gel→Sol→Gel→Sol Transitions
Angewandte Chemie International Edition, 2023 AbstractComplex non‐equilibrium phase behaviors are a hallmark of natural self‐assembling systems. Here we show how intricate phase transitions can be achieved through a chemically fueled reaction cycle to yield autonomous sol→gel→sol→gel→sol transitions.
