process is an out-of-equilibrium dynamic
process driven by chemical fuels. Such processes play very important
roles in different types of biochemical process in nature. Herein,
a dissipative hydrogel system based on the multiple-carboxyl tetraphenylethylene MCTPE 1 and 1-ethyl-3-(3-(dimethylamino)propyl)carbodiimide
(EDC) was constructed successfully. In the hydrogel system, an aqueous
solution of MCTPE 1 could be converted into the hydrogel
rapidly using EDC as the chemical fuel. After that, the obtained hydrogel
began to dissolve back to the solution state slowly. On the basis
of this chemical-fuel-driven dissipative system, a writable in aqueous
solution and self-erasable hydrogel material was achieved.
