Abstract

Cyclic polysilanes are of special interest because they exhibit unusual electronic, physical and chemical properties, resembling those of aromatic and poly-unsaturated compounds [1]. For example, cyclic polysilanes have electronic transitions in the UV-VIS region, form electrondelocalized anion radicals upon reduction and cation radicals upon oxidation, in which the odd electron is distributed over the ring, form charge-transfer complexes with n-acceptors, and exhibit substituent effects. It seems that delocalization of the Si-Si σ-electrons over the ring, as first suggested by Pitt [2], accounts for these unusual properties. The synthesis, structure, chemical reactions and photolysis of cyclic polysilanes are described in a recent review[3].
