Porphyrin and Their Derivatives Synthesis, Characterization, and Applications

Dear Colleagues:

Porphyrins represent a widely investigated class of macrocyclic coordination compounds with applications in multidisciplinary fields. They exhibit a strong absorption in the visible spectral region and near-infrared, while ordered aggregates consisting of self-assembled porphyrin molecules may enable ultra-fast energy and electron transfer because of the delocalized excited states present in the aggregates as compared to the localized π–π^∗ transitions within the monomer. Porphyrins and their derivatives, such as porphyrin triads, liquid–crystalline porphyrins, porphyrin dendrimers, porphyrin-containing oligomers, and main-chain porphyrin polymers have been widely used as photosensitizers in photodynamic, photothermal therapy (PTT and PDT) and dye-sensitized solar cells (DSSCs), as fluorescent materials in chemical sensors as light harvesting elements in organic solar cells (OSCs), and as charge transport materials in both OSCs and perovskite solar cells (PSCs). The aim of this Special Issue is to highlight the various aspects of their synthesis, functionalization, structural modification, optoelectronic properties, and potential applications, with emphasis on photodynamic therapy, photovoltaics, and sensors. Articles reporting novel results or reviews are welcome.

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. Materials 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 2600 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.
