Mesostructured Non-Oxidic Solids with Adjustable Worm-hole Shaped Pores: M-Ge-Q (Q = S, Se) Frameworks Based on Tetrahedral [Ge4Q10]4- Clusters

A new class of mesostructured semiconducting materials, M-Ge-Q (Q=S, Se), has been synthesized using aqueous electrostatic supramolecular self-assembly. The pores in these mesostructured materials are adjustable and are filled with surfactant molecules (see Figure) which can be removed by heating in an inert atmosphere without collapse of the framework.
