Intelligent writable material based on a supramolecular self-assembly gel†
Abstract
A simple dual acylhydrazone-functionalized gelator (G1) has been designed and synthesized, and it was found to form a supramolecular organogel (G1-gel) in a mixed solvent of DMF–H2O. The gelator solution shows brilliant blue light upon mixing with Mg2+; this blue light can be erased by saliva or CO32−. Owing to this characteristic, a smart erasable writable material was prepared.
