PRECURSORS OF SUPRAMOLECULAR CAPSULE FOR AMMONIUM IONS, SUPRAMOLECULAR CAPSULE FOR AMMONIUM IONS, SELF-ASSEMBLY METHOD AND DISASSEMBLY METHOD FOR THE SAME

摘要

A supramolecular capsule for ammonium ions is provided to transport selectively ammonium ions by binding them in a cavity and control package, transport and release of ammonium ions through self-assembly and disassembly itself. Precursors of supramolecular capsule for ammonium ions are represented by the formula(1), wherein R is methyl or ethyl; a nitrogen of pyridine group coordinately binds with a transition metal; and a nitrogen of phenyl oxazoline group forms a hydrogen bonding with hydrogen of ammonium ions. A supramolecular capsule for ammonium ions as a dimmer of the precursors of supramolecular capsule for ammonium ions is represented by the formula(2), wherein X is a transition metal and R is methyl or ethyl. The supramolecular capsule for ammonium ions is self-assembled by mixing the precursors of supramolecular capsule for ammonium ions with a trans type transition metal complex in a solvent selected from solvents having dipole moment of 2.91D or less and its mixture, wherein the transition metal is palladium, and the solvent having dipole moment of 2.91D or less is dichloromethane, chloroform or acetone. The supramolecular capsule for ammonium ions is disassembled by adding triethyl amine into the supramolecular capsule for ammonium ions.
