| Outline of Final Research Achievements |
We succeeded in synthesizing and isolating of stable bis(silyl radical) connected by disilane chain, and determined its ground state as triplet. Furthermore, bis(germyl radical)s connected by meta-phenylene and para-phenylene spacer were also synthesized. Meta-phenylene bridged bis(germyl radical), which is non-Kekule; molecule;, has triplet ground state. One the other hand, para-phenylene bridged bis(germyl radical) has singlet ground state, but its singlet-triplet energy gap is quite low. Therefore, it was found that para-phenylene bridged bis(germyl radical) exists as an equilibrium mixture of singlet ground state and thermally accessible triplet excited state at high temperature such as room temperature.
