The spectroscopic characteristics of a series of di- and tetra-naphthyl-substituted siloles will be described. Siloles have received much recent attention due to the unusual luminescence properties of many of the members of this class of compounds. The UV-Vis absorption and emission behavior, including luminescence quantum yields, luminescence lifetimes, and aggregation-induced emission (AIE) of several naphthyl-substituted siloles will be reported and compared to each other and a tetraphenylsilole, with particular emphasis on the effects of the positions of substitution on the silole core ring and the point of attachment on the naphthyl substituents.
