Description:
<jats:p><jats:bold>Scheibe agregates (J‐aggregates)</jats:bold>, 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. <jats:boxed-text content-type="graphic" position="anchor"><jats:graphic xmlns:xlink="http://www.w3.org/1999/xlink" mimetype="image/gif" position="anchor" specific-use="enlarged-web-image" xlink:href="graphic/must001.gif"><jats:alt-text>magnified image</jats:alt-text></jats:graphic></jats:boxed-text></jats:p>
