When
the caged germasesquioxanes hexakis(cyclohexylgermasesquioxane) and
hexakis(n-octylgermasesquioxane) (GT6Cy and GT6Oc) were irradiated with γ-rays
in 2-methyltetrahydrofuran (2-MTHF) glass matrices at 77 K, anisotropic
ESR signals ascribed to their radical anions were observed. DFT calculations
of a model radical anion, [hexakis(methylgermasilsesquioxane)]− (GT6Me–), indicated unsymmetrical distribution of the
SOMO (singly occupied molecular orbital), in agreement with the anisotropy
of the ESR signals. To better understand the electronic states of
the caged germasesquioxanes, hexakis(dimethylaminophenylgermasesquioxane)
(GT6An) was prepared
and its photoluminescence (PL) properties were investigated. Interestingly,
the PL efficiency of GT6An was much lower than that of dimethylaniline itself, likely
because of the electron transfer from the photoexcited dimethylaniline
unit to the germasesquioxane cage.
