Efficient Spontaneous and Stimulated Emission from 1,4‐Bis(2,2‐diphenylvinyl)benzene Single Crystals with Cross‐Dipole Stacking

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.
