Dear Colleagues,

Organocatalysis represents one of the most exciting and rapidly developing research fields in organic chemistry, becoming the third pillar after transition metal catalysis and biocatalysis. Using nonmetal catalysts in organic syntheses presents a lot of advantages, such as less toxicity and pollution, ease of handling, less sensitivity to air and moisture, lower cost, thus making this option more economical and less harmful to the environment than applying traditional organometallic catalysts. In this regard, low-cost and environmentally benign organocatalysis may be an effective tool for the synthesis of complex organic molecules. Moreover, using chiral organocatalysts can make asymmetric syntheses possible.
In addition, electrochemical and photochemical reactions applying organic molecules as mediators and catalysts can offer mild, alternative methodological strategies towards green chemistry.
This Special Issue aims to cover recent research and advances in the field of metal-free catalysts, photoredox- and electrocatalysis. Novel mechanistic and investigatory studies on catalysis, design and synthesis of organocatalysts, their applications in the preparation of products important in the pharmaceutical or material sciences, as well as recycling are welcomed in this issue as full papers, communications, and mini-reviews.

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 papers will be 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 2000 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.
