Stable Radicals: Synthesis and Applications

Dear Colleagues,

More than 120 years have passed since Moses Gomberg discovered the triphenylmethyl radical. Since then, these types of strange open-shell molecules, which are usually thermodynamically and kinetically unstable, have become key to the development of important areas of chemistry and materials science. Throughout all this time, many radicals stable enough to be isolated as pure compounds or crystals have been discovered and characterized via spectroscopic techniques, in particular via magnetic susceptibility measurements, absorption spectroscopy and, above all, electron paramagnetic resonance spectroscopy (EPR).

Today, organic radicals are widely used in areas as diverse as plastics and rubber manufacturing, agriculture or biochemistry. They have applications as building blocks for molecule-based magnets, spintronic devices such as spin transport devices, quantum computers and spin valves, conducting materials and batteries, optoelectronics, etc., and thinking about biomedical applications, bioimaging such as contrast agents for MRI, biosensing, antioxidants or photo-triggered therapies.

In this Special Issue, we would like to reflect on all current trends and applications of organic radicals.

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 250 words) can be sent to the Editorial Office for assessment.

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.
