  The surfactant assisted exfoliation and non-covalent functionalization of
two-dimensional layered materials, like graphene, transition metal
dichalcogenides, etc., has extraordinarily been propelled forward within the
last 5 years. Numerous molecules have been designed and attached to the
exfoliated layers, and based on their outstanding properties, perylene based
dyes have become one of the most frequently used {\pi}-detergents. Therefore,
the prospect of this micro review is to summarize the most prominent
achievements in this rapidly progressing field of research.
