Scheibe agregates (J‐aggregates), highly ordered systems of strongly interacting chromophores (e.g. see figure), are characterized by a strong and narrow absorption band shifted to lower energy with respect to the band of the monomer, and a narrow resonance emission band with a very small Stokes shift. The formation of such aggregates, their organization and reorganization, their structure and their optical and photophysical properties are reviewed.
