Phthalocyanines (Pcs) are organic aromatic molecules widely employed in the field of molecular materials mainly due to their exceptional stability and interesting optical properties, i.e. intense absorption in almost all the visible region and high polarizability, derived from their delocalized electronic system[50]. Like their porphyrin relatives, they are also frequently used as donor units in donor-acceptor ensembles. Moreover, the chemical versatility of Pcs makes possible the introduction of different types of metals in their central cavity and their peripheral functionalization with electron-withdrawing groups, thus allowing the modulation of their electronic properties.
