A solvent-controlled photoresponsive ionic hydrogen-bonded organic framework for encryption applications

Chem Commun (Camb). 2024 Mar 6. doi: 10.1039/d4cc00701h. Online ahead of print.ABSTRACTTwo novel ionic hydrogen-bonded organic frameworks (iHOF-17 and iHOF-18) were obtained by integrating organosulfonic acids with amidine salts. Among them, iHOF-18 exhibits fast, reversible, and high-contrast UV-induced photochromic properties, and this property is solvent-controlled. This work provides valuable insights for designing advanced anti-counterfeiting techniques and encryption applications.PMID:38444288 | DOI:10.1039/d4cc00701h
