Special Issue Information
Dear Colleagues,
The development of rare earth chemistry has witnessed spectacular growth in the last decades, where the design and application of complexes as polymerization catalysts has occupied an especially important place. Rare earth catalysts are nowadays widely involved in the field of coordination polymerization as they can produce high added-value stereoregular polymers or copolymers. In that frame, the design of well-defined ligands in order to tune the activity or selectivity of the polymerization catalysts plays a key role. Rare earth polymerization catalysts were first mainly dominated by metallocene complexes, before the more recent development of non-Cp, post-metallocene systems. The emergence of undercoordinated cationic catalytic species was also a breakthrough in the field, leading to extremely active and selective systems towards olefins and dienes. More recently, in a context of sustainable chemistry, many efforts have been made to develop ring opening polymerisation (ROP) catalysts of cyclic esters to produce various biodegradable polymers. The present Special Issue “Rare Earth Complexes as Polymerization Catalysts” aims at reflecting the recent advances in that research field. Submissions are welcome in the form of original research papers or short reviews that reflect the state of the research in the field of rare earth polymerization catalysts on the following topics: Stereoselective rare earth (co-)polymerization catalysts of olefins and/or conjugated dienes, ring opening polymerization (ROP) of cyclic esters, polymerization mechanisms involving rare earth catalysts, and computational calculations on rare earth polymerization catalytic systems.

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. Catalysts is an international peer-reviewed open access monthly 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 2200 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.
