Chirality and Spatial Organization of Multi-Porphyrinoids

Dear Colleagues,

Chirality is a fundamental property of the universe that has an enormous impact on different organic/inorganic materials, living organisms, and human beings. The basic principle of chirality is existence of an object in two mirror image forms that are not superimposable. This phenomenon is widely seen in various branches of chemistry at scales ranging from single molecules to complex supramolecular and nano-scaled assemblies. Static chirality is generally associated with a single molecule or group of molecules belonging to the C_n or D_n point groups, with the simplest example of sp³ carbon atom bonded to four different substituents. The dynamic processes of chirality generation, modulation, transfer, amplification, etc., are termed chirogenesis. Such processes represent a fast-growing and interdisciplinary field of research and are widely seen either in many natural systems (such as the DNA double helix, the secondary alpha-helix structure of proteins, lipid membranes, saccharides, heme proteins, and other biological molecular objects) or in various artificial molecular architectures that are of prime importance for both fundamental science and a number of practical applications (in areas such as pharmacology, agrochemistry, perfumery, food industry, materials and polymer sciences, enantioselective catalysis, nonlinear optics, nanoscience and nanotechnology, molecular devices, chemical sensors, and others).

Porphyrinoid-based chromophoric systems are well suited for studying various processes related to chirality and chirogenesis, owing to their spectral and physicochemical properties, easy handling, versatile modification, great biological importance, wide applicability, as well as superior propensity to form various supramolecular assemblies. Among these systems, multi-porphyrinoids are of particular interest due to their superior ability to amplify and control chirogenic processes via specific spatial organization.

This Special Issue will cover the wide range of synthetic, structural, and photochemical factors influencing the chirality and spatial organization of multi-porphyrinoids.

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.
