Resumen:
Highly ordered mixed framework mesoporous cubic (Im3m) or 2D hexagonal (p6m) thin films of
(M12x(Si?R)x)O22x/2 bearing organic groups (M = Ti or Zr, R = propylamine, mercaptopropyl or
phenyl, x¡0.2) are obtained by one-pot dip-coating. A second organic function (R9 = hexadecyl,
phenyl, sulfonate?) can be added by post-grafting with a molecule presenting a chelating group
capable of anchoring to theMsites (phosphate, phosphonate, polyhydroxyphenol, carboxylate?)
and a second organic group. This two-step procedure leads to bifunctional accessible mesopores.
The role of post-synthesis stabilisation treatments, the alternative processes for template
extraction, and the pore accessibility towards a second function are presented and discussed.Im3m) or 2D hexagonal (p6m) thin films of
