Porphyrins belong to the most important classes of functional materials. These unique ligands play fundamental roles in Nature in, for example, energy and oxygen processing (. photosynthesis and respiration). Thus, these macrocycles are aptly characterized as “pigments of life”. Due their fascinating properties, porphyrins are used more and more in materials science and applications, such as photovoltaics ans optoelectronics. A most intriguing aspect of porphyrin chemistry is the expansion of the π-system and, in the extreme, the formal embedment of the system into the graphene lattice.
In the presentation, the syntheses and characterization of novel porphyrins carrying polycyclic aromatic hydrocarbons such as hexabenzocoronenes is shown. Also included are precursor syntheses as well as post-functionalizations of these macrocycles. Some of their properties will be discussed, i.e., solid state structures, absorption and emission characteristics, and possible applications.
