Abstract

The invention provides a long-chain p-nitrobenzoylhydrazone gelator. One side of the gelator is three long alkyl chains which have 16 C and are obtained through etherification, and the three long alkyl chains can form initial driving force for gelation through mutual action among carbon hydrogen; middle -NH obtained through a hydrazinolysis reaction can form stable gel with -CH and C=O adjacent to -NH through action of intermolecular hydrogen bonds and can also form corresponding binding sites with metal ions through coordination so as to further form the organic metal gel; the formed organic metal gel can realize rapid highly-selective fluorescent recognition of I<-> in water and is obvious in color changes, which enables detection with the naked eyes to be conveniently and rapidly realized; and the formed organic metal gel has good stability, is easy to store and carry and convenient to use and can be used for writing and storage of confidential materials.
