| Research Abstract |
The stable free radicals on the heavier group 14 elements (Si, Ge, Sn) were studied by UV-photoelectron spectroscopy and cyclic voltammetry, in order to determine their redox properties. Isomeric para- and meta-disilaquinodimethanes were synthesized and characterized; the para-isomer was shown to possess a singlet ground state with a closed-shell quinoid form, whereas the meta-isomer was shown to manifest a robust triplet ground state.
