摘　　要：Developing chemical systems capable of executing multipath nonequilibrium processes provides valuable insights into the study of multistage dissipative structures in living systems.Here,we report a nonequilibrium multipath evolution in a three-state supramolecular system,which is clarified by associating it with a multibranch selection structure.This system is constructed by synergistically combining an assembly-induced sol-gel transition with the color change of an acid-base indicator.Depending on the initial condition and chemical fuel composition,this system can execute five distinct nonequilibrium processes.In addition,the set of structured programming can be replayed by repeatedly introducing the chemical fuel.It is further utilized to explore the applications of information encryption and establish its universality.These findings offer novel avenues for future transient material design and may make significant contributions to systems chemistry.
