Organic single crystals with cross‐dipole stacking based on 1,4‐bis(2,2‐diphenylvinyl)benzene are prepared. X‐ray diffraction shows that adjacent molecules in the single crystal adopt a rotational angle of ≈62°. Such a stacking mode is highly beneficial for spontaneous and stimulated emission, resulting in high solid‐state fluorescence efficiency and excellent amplified spontaneous emission characteristics.
