Bipyridines: Synthesis, Functionalization and Applications

Dear Colleagues,

This Special Issue is dedicated to all aspects of bipyridine chemistry. Bipyridines represent the important family of heterocycles, having two pyridines directly linked together giving either symmetrical isomers (2,2′, 3,3′, and 4,4′) or asymmetrical ones (2,3′, 2,4′, and 3,4′). These compounds, especially the 2,2’ and 4,4’ isomers, are known as excellent ligands in coordination chemistry, with an impact in many fields including catalysis and material chemistry. Besides coordination to metals, the nitrogen atoms of bipyridines are able to interact with different molecules through non-covalent interactions (hydrogen or halogen bonds), leading to supramolecular structures with interesting properties. Another important aspect of bipyridine chemistry is the possibility of introducing chirality through ring functionalization or restricted rotation (atropisomery), thus increasing their importance in asymmetry-based applications. Finally, with regard to 4,4’-bipyridines, the quaternization of nitrogens generates viologens, which are known for their good electrochemical properties.

This Special Issue welcomes the submission of papers based on original research, or reviews that describe the synthesis of functionalized bipyridines and their applications, ranging from novel synthetic transformations to the design and development of new materials.

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.
