Influence of the substituents and the number of silafluorene units in 1–4 on their optical properties was investigated. Extensive study of the X‐ray crystal structures of 1–4 was undertaken to analyze and qualitatively estimate the role, extent, and influence of silafluorene moieties’ interactions on solid‐state fluorescent properties.
