摘要：

Even at sub-stoichiometric Se loading into the supercages of Sr-Y zeolite, significant concentrations of Se-8 rings form in addition to the open chain structures. This material provides an excellent medium for the investigation of the vibrational and UV/VIS absorption spectra of isolated Se-8 molecules under well-defined conditions. The potential of these nanostructured composite materials has not yet been fully exploited, and a complete understanding of the molecular structure of such encapsulates is prerequisite for tailoring new materials for optoelectronic purposes.
