Metal phosphate- and phosphonate-based nanoarchitectured materials offer a unique opportunity to design hierarchically porous nanomaterials consisting of interconnected micropores, mesopores, and macropores. Due to their strong affinity toward the metal centers, the phosphate and phosphonate moieties act as ligand sites/linkers to form a wide spectrum of nanoarchitectured by: Routes to new mixed-divalent metal phosphonate materials Author: Menaa, Bouzid.

Esters derived from the simplest carboxylic acids are commonly named according to the more traditional, so-called "trivial names" e.g. as formate, acetate, propionate, and butyrate, as opposed to the IUPAC nomenclature methanoate, ethanoate, propanoate and butanoate.
