Abstract This chapter describes the emission behavior of molecules on the surface
of layered materials. Emission properties of molecules depend on their surrounding
environment. Even in homogeneous environments, this emission behavior depends
on solvent effects such as viscosity, permittivity, polarity, and so on. While the
chemical reaction media provided by layered materials is the analog of solvent
effects, the effect of layered materials induces important changes in the properties
of the molecule. For example, the emission intensity could be enhanced 100 times by
the complex formation with layered materials. Despite the drastic effect of layered
materials on the photochemical properties of molecules, the use of layered materials
is limited due to some factors. One of these factors is the complicated complex
formation behavior of molecules on layered materials. This sometimes includes
