Redox‐active G‐quadruplex hydrogels were prepared by dynamic boronate ester formation between ferroceneboronic acid and guanosine. Dynamic boronate esters imparted thixotropic and 3D‐printability to the hydrogel. Initially, the ferrocene moiety was oxidised to produce a weaker ferrocenium‐based green hydrogel. However, the less stable ferrocenium converted into more stable ferrocene to produce a hydrophobic, water‐stable and robust hydrogel.
