A functionalized porous crystalline material is disclosed exhibiting an X-ray diffraction pattern with at least one peak at a position greater than about 1.8 nm d-spacing with a relative intensity of 100. The crystalline material comprises a framework including metal atoms, oxygen atoms and at least one organic group bonded between at least two of said metal atoms so as to be integral with said framework, and wherein said organic group has at least one sulfonate moiety bonded thereto.

Syntheses of new poly(trifunctional-silyl)alkanes, which are potent coupling agents of hybrid organic–inorganic materials have been thoroughly examined. Optimization of the Benkeser reaction using chloroform, trichlorosilane and tri-n-butylamine (respective ratios 1:4.5:3) afforded bis(trichlorosilyl)methane isolated as bis(triethoxysilyl)methane after ethanolysis (overall yield 60%).
