Two new strongly AEE active (I/I0 ≈ 94) tetraphenylsilole-containing cyclosiloxanes with cyan emissions (λem = 500 nm) and ~100% solid state fluorescence quantum yields are reported. The intra- and intermolecular C-H•••π interactions in the crystal play a major role in the observed high solid state fluorescence quantum yields.
