“…The necessary aqueous medium with controlled acidity and the limited photostability of 15 mean restrictions for many applications. The ESPT mechanism can be also realized with the more stable perylene dyes such as 16 (RN 1018856-45-5) [82] even in more lipophilic media where amines may be applied as proton acceptors. The ESPT mechanism allows a separation between absorption and fluorescence spectra for 16; see Figure 13.…”

The handling and control of light is becoming more and more attractive in science and technology such as data processing and requires functional chromophores. As a consequence, fluorescent materials are of special importance because they allow the processing of light energy. Thus, basics of fluorescence are reported as prerequisites for planning complex functional structures. Various fluorescent systems are presented beginning with historic observations followed by a detailed discussion of light absorption and emission indicating fluorescent chromophores as molecular resonators; molecular dynamics and intermolecular interactions are leading to complex functional materials.
