One example of these systems is porphyrin on highly oriented pyrolitic graphite.
The most common type of these show a "root three by root three R 30 degrees" structure with a tilt angle of twenty eight degrees. A recent AFM study showed the possibility of a Langmuir-like film at the substrate-solution interface in these systems. They are not surfactants, but these entities can be used to control wetting properties as they allow for contact angle variance with respect to concentration. One example of these systems is porphyrin on highly oriented pyrolitic graphite. The most popular system of this type consists of n-alkanethiols adsorbed to Gold 1-1-1. For 10 points, name these ordered molecular assemblies on the surface of a solid that are able to spontaneously form into superstructures.
