Abstract
Amphiphilic porphyrins with a bola-type arrangement of trimethylammonium headgroups can be used to generate M41S-type silica mesostructures with a lamellar topology and alternating organic-inorganic layers. Within the organic layers, the porphyrin entities are aggregated as shown by UV-Vis spectroscopy. The use of a bola amphiphile as structure-directing agent extends the possibilities of surfactant-controlled assembly of inorganic structures. In addition, the direct functionalization of the organic part of organic-inorganic hybrid nanostructures is possible due to the combination of the amphiphilic function with that of a chromophore.
