Global Porphyrin System

These pages, in construction, will introduce the conceptual approach to porphyrinoids (porphyrin -or macrocyclic tetrapyrroles- structural variants) from annulenes. Numerous papers have been published on this concept. We would like here to present the structural variations in a schematic way by links-clicking that leads to the particular molecules. This section of the site includes as well page(s) with links to educational sites in the field of porphyrin chemistry and related (courses and tutorials).

At this point, Global Porphyrin System (GPS), is a rough draft and errors may be found. Please be patient.
