FUNCTIONAL BINAMIDINE, PREPARATION METHOD THEREOF, AND ION SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a novel functional binamidine, a preparation method thereof, and an ion sensor containing the functional binamidine, particularly, an ion sensor capable of easily detecting ammonium ion by identification of change in tone by the naked eyes. SOLUTION: The binamidine comprises two benzo-crown ethers introduced to a binamidine framework as the largest characteristic, and has visible absorption by conjugation with two aromatic rings. This binamidine is a binamidine-crown hybrid compound using the visible absorption by the conjugation as a coloring source, and introducing the crown ethers as an ion recognition part.
