Color‐Tuned, Highly Emissive Dicyanodistyrylbenzene Single Crystals: Manipulating Intermolecular Stacking Interactions for Spontaneous and Stimulated Emission Characteristics

Solid-state, luminescent, aggregation-induced enhanced emission (AIEE)-active dicyanodistyrylbenzene-based organic π-conjugated materials, i.e. α-MODCS, α-MODBDCS, β-MODCS, and β-MODBDCS, are designed. In virtue of the systematically substituted modular molecular systems combined with thorough structural analyses, photophysical studies, and electronic structure calculations, the spontaneous and stimulated emission properties are quantified and rationalized from a perspective of well-established structure–property correlations.
