Cutting-Edge Research for Photopolymerization

Dear Colleagues,

Photopolymers are appealing materials that have now found applications in dentistry, coatings, inks, and adhesives, but also in emerging fields such as 3D and 4D printing. Although photopolymerization was traditionally done in the UV range, recently, a great deal of interest has been devoted to developing visible light photoinitiators, addressing the manipulator safety concerns but also offering a broader variety of structures that can be used as photoinitiators. Parallel to this, with regard to the toxicity concerns raised by the use of transition metals, organic compounds that can act as photoinitiators of polymerization are actively being researched by both the academic and industrial communities. The development of new monomers is also largely reported. New photosensitive resins based on well-selected and developed photoinitiators/monomers/oligomers/additives/fillers are in the heart of many studies. Many new applications (3D/4D printing, composites, biomedical devices) are under development. Researchers in the field are cordially invited to submit relevant manuscripts concerning the development of new photoinitiators, photosensitive resins, and photopolymers for a Special Issue entitled “Cutting Edge Research for Photopolymerization”, within the journal Molecules. Perspectives and reviews in this active research field are also 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 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.
