Figure 4.
Large planar macrocycles such as porphyrins and phthalocyanines tend to adsorb cofacially on surfaces such as highly ordered pyrolytic graphite (HOPG), Au(III), NaCl, and other atomically smooth substrates. Here Ni(TPP) and PcF16 are deposited on HOPG as well as a 2:1 mixture. Reproduced from ref. [117] with permission of the copyright holders.
