Novel organosoluble filiform zirconium phosphonates with a layered mesoporous backbone

Abstract

A novel type of organosoluble and filiform zirconium phosphonate with a layered mesoporous backbone functionalized with hydroxyl and amino groups was prepared by the reaction of a functionalized phosphoric acid with ZrOCl₂·8H₂O. These filiform zirconium phosphonates has good solubility (0.21–0.71 g mL⁻¹) in certain organic solvents (such as toluene, chloroform, tetrahydrofuran and ethyl acetate), are immiscible in some other solvents (hexane, cyclohexane, petroleum ether and ethanol), and can be recovered from organic solvents in high yield (95–100%) by precipitation.
