Webb20 jan. 2024 · Schiff Base is a compound with the generic structure R2C=NR'. Schiff bases are subclasses of imines, that, depending on their structure, can be secondary aldehydesor secondary ketimines. The term is frequently interchanged with azomethine (which refers to secondary aldimines). These compounds were named after Hugo Schiff, an Italian … WebbSchiff base bonds formed by primary amines and aldehydes are attractive for the construction of self-healing and injectable hydrogels. However, biomedical applications of the Schiff base–based (SB) hydrogels are usually limited by their inherent low stability due to the rapid exchange dynamic of the Schiff base bond under physiological condition.
