| Outline of Final Research Achievements |
Decasilahexahydrotriquinacene (1) and decasilaisotwistane (2) were synthesized, and their structures and electronic properties were studied. Compounds 1 and 2 were synthesized by the reduction of tris(1,3-dibromo-2-trisilanyl)methylsilane with 6.3 equiv of potassium graphite. The structure of 1 was determined by NMR spectra and theoretical calculations. The structure of 2 was determined by X-ray crystallography. The UV spectra of 1 and 2 show that the lowest energy absorption band of 1 is bathochromically shifted compared with that of 2. This result was analyzed by theoretical calculations of 1 and 2.
