Abstract
Organic/inorganic complex porous materials are disclosed having a main skeletal chain containing metal atoms, oxygen atoms, and organic groups. Preferably, the metal atoms, oxygen atoms and organic groups are bound by ionic bonds and/or covalent bonds, and the organic group is bound to at least two metal atoms in the main chain of the skeleton of the porous material. More preferably, 60% or more of the total pore volume in the porous material has a pore diameter in a range of ±40% of the pore diameter, as determined from the maximum peak in a pore size distribution curve. Alternatively, at least one peak is present at a diffraction angle that preferably corresponds to a d value of at least 1 nm in an x-ray diffraction pattern. Method of making such organic/inorganic complex materials are also disclosed.
