Special Issue Information
Dear Colleagues,
Porphyrazines and phthalocyanines, also known as tetraazaporphyrins, are synthetic members of the porphyrinoid family. They comprise pyrrole or isoindole moieties, respectively, linked by nitrogen bridges in the form of macrocyclic rings, able to bind metal cations at their center. This binding imparts unique physicochemical and electrochemical properties, tunable by substituting the central cation or functionalizing the heteroaromatic rings. Porphyrazines and phthalocyanines feature an extended aromatic system with 18 conjugated π-electrons, contributing to their stability and optical properties, including visible and ultraviolet light absorption. Their ability to absorb light and generate reactive oxygen species through energy transfer mechanisms is leveraged in photodynamic therapy (targeting cancer cells and microorganisms) and in photocatalysis. Additionally, tetraazaporphyrins' ability to emit fluorescence after light irradiation is employed in photodynamic diagnosis. Porphyrazines and phthalocyanines can also catalyze oxidation and reduction reactions, especially when coordinating d-block metal ions like iron and manganese, which enables them to serve as electrocatalysts.
In this Special Issue, entitled “Synthesis and Characterization of Peripherally Functionalized Porphyrazines and Phthalocyanines”, we invite researchers worldwide who contribute to the field and publish studies highlighting the diverse applicability of tetraazaporphyrins.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
