We are happy to be Guest Editors of this Special Issue of Molecules, dedicated to “Porphyrins and Phthalocyanines”. Porphyrins constitute a family of macrocycles that are ubiquitous in nature, playing important roles in numerous biological functions. Their 18 p-electron, aromatic, tetrapyrrolic structure represents far more than the sum of its parts, giving rise to a variety of physicochemical properties that cannot be deduced from those of pyrroles. Although the beginnings of porphyrin chemistry can be traced back to Hans Fischer in the 1930s, the synthesis of these macrocycles, as well as the preparation of new congeners, has been a matter of continuing scientific interest. Phthalocyanines represent the best known synthetic porphyrin analogues, being one of the most widely studied macrocyclic compounds. In addition, the synthesis of expanded, contracted, and intrinsically unsymmetrical porphyrin and phthalocyanine analogues remains an expanding topic. The scope of porphyrin science is enormous, ranging from chemical synthesis and molecular characterization to supramolecular organization, spectroscopy, electrochemistry, bioinorganic chemistry, photochemistry and photophysics, clinical medicine, and materials science, among others. This Special Issue is aimed at covering recent advances in the synthesis, characterization, and applications of porphyrins, phthalocyanines, and their analogues. We hope that these fields will be represented by both reviews and original chemical research reports that represent your contributions to this volume.

Abstract: This work aims at studying the potential replacement of the toxic solvents that are normally employed for the synthesis of phthalocyanines, e.g. dimethylaminoethanol, nitrobenzene and -chloronaphthalene, with greener alternatives. Anisole, glycerol and their mixtures have been investigated as reaction media for the tetramerization of phthalonitriles with the aim of developing new sustainable and scalable synthetic protocols with comparable or lower E-factors and costs with respect to the existing ones. Salts of several divalent first-transition metal cations [(Co(II), Ni(II), Cu(II) and Zn(II)) were used and different bases were tested, depending on the chosen substrates and reaction conditions. Unsubstituted phthalocyanines were synthesized to analyze the behavior of the different metals in terms of reactivity in the new reaction media, resulting in a general Cu > Ni > Co > Zn trend, while tetra-tert-butyl substituted derivatives were investigated to evaluate the influence of an alkyl bulky moiety on the tetramerization efficiency. Furthermore, the statistical synthesis of the unsymmetrical tri-tert-butyl-iodo zinc phthalocyanine in glycerol/anisole with KOH as a base gave a 26% yield, comparable with those already published in literature. Our results provide insights into the investigation of new reaction environments and in the understanding of their strengths and weaknesses, with a view to further increasing the sustainability of the synthesis of macrocyclic molecules and intermediates with high added value.
