Abstract
Mesostructured non-oxidic materials with cubic Ia-3d symmetry were prepared by linking [Sn2Se6]4- clusters with Pt2+ in the presence of surfactant molecules. The use of long chain pyridinium-based surfactants (octadecyl- and eicosadecyl) afforded materials with exceptionally high cubic pore order and single-crystal particle morphology. By contrast trimethylammonium-based surfactants produced cubic mesostructured solids with inferior overall quality. We have also synthesized materials with significantly lower surfactant content by increasing the Pt 2+:[Sn2Se6]4- molar ratio, while maintaining the cubic pore symmetry. All materials are semiconductors with energy band-gap in the range 0.9g
