A new class of mesostructured semiconducting materials, M-Ge-Q (Q = S,Se) were synthesized and characterized. The materials possess an amorphous, three-dimensional framework structure in which simple adamante clusters are the basic building blocks. The application of formamide led to a hexagonally ordered pore structure and a different stoichiometry, whereas, H2O/alcohol mixtures favored disordered pore structure with worm-hole character. All compounds are wide bandgap semiconductors, the Se phases showing lower values than the sulfide analogs.
