Special Issue Information

Dear Colleagues,

Metal complexes have emerged as versatile and indispensable compounds in modern chemistry. They have some of the most challenging and diverse structures in this field; due to their unique electronic and stereochemical properties, they offer a plethora of applications spanning from materials science to catalysis and medicinal chemistry.

The synthesis, characterization and applications of metal complexes is therefore a very relevant area of research in modern chemistry that fully justifies a dedicated Special Issue. The goal of this Special Issue is to gather a collection of manuscripts that report the synthesis and characterization of such compounds and highlights their important applications in chemical and physical sciences, as well as in medicine.

Hence, potential topics of interest include, but are not limited to, the following:

  • Synthetic methods;
  • Spectroscopic methods;
  • Structural determination using different diffraction techniques;
  • Magnetic properties;
  • Optical properties;
  • Applications in materials science;
  • Therapeutic applications;
  • Applications in catalysis.

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. 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.

Abstract
An asymmetric two-arm polypyridine ligand 4′-{4-[4-(2,2′-dipyridyl)phenyl]}-2,2′:6′,2′-terpyridine (TPY-Ph-BPY) with double coordination units was synthesized using the one-step Suzuki reaction. The metallic supramolecular film was subsequently obtained by the Fe2+-induced self-assembly method at the CHCl3-H2O interface, which [...] Read more.
An asymmetric two-arm polypyridine ligand 4′-{4-[4-(2,2′-dipyridyl)phenyl]}-2,2′:6′,2′-terpyridine (TPY-Ph-BPY) with double coordination units was synthesized using the one-step Suzuki reaction. The metallic supramolecular film was subsequently obtained by the Fe2+-induced self-assembly method at the CHCl3-H2O interface, which displayed a distinct flat and continuous morphology. The supramolecular film-coated ITO electrode demonstrated a reversible electrochemical redox behavior with pronounced color changes between purple and light green. Its solid-state electrochromic device had an optical contrast (ΔT%) of 26.2% at λmax = 573 nm with balanced coloring (tc = 2.4 s) and bleaching (tb = 2.6 s) times and a high current efficiency of 507.8 cm2/C. Moreover, good cycling stability with a long-term reversible color change was observed beyond 900 cycles. These results suggested the promising potential of the TPY-Ph-BPY-Fe(II) supramolecular film for electrochromic applications. Full article
