Notes:
Single crystal x-ray crystallographic analysis of tert-butyloctasilacubane showed that a new polymorphic form (β form) exists with a slightly modified shape of the Si cage as compared with the previously reported form (α form) [K. Furukawa, M. Fujino, and N. Matsumoto, Appl. Phys. Lett. 60, 2744 (1991)]. Spectroscopic investigations of the single crystal indicate that the electronic band gap and luminescence band position differ by ∼0.4 eV between the polymorphs, signaling the sensitivity of the electronic structure to the distortion of the octasilacubane framework.
