Organically pillared microporous zirconium phosphonates
Abstract
There is great technological interest in the design of multifunctional microporous materials, particularly those with pores in the 10–20 Å range. The many attempts to achieve this goal through cross-linking zirconium phosphate-like layers by use of several types of diphosphonic acids will be described. A variety of functionalized pillared materials are also described with potential as sorbents and
