Low-temperature absorption and fluorescence spectra of a series of permethylated oligosilanes Si Me in their all-anti form permits the identification of Si Me as the shortest chain capable of supporting a large-radius exciton in its relaxed 7 1 6 lowest singlet excited state, while Si Me and shorte
