Spotlight Collection: Metallocycles and Metallocages

We are delighted to announce our new spotlight collection on Metallocycles and Metallocages. Spotlight Collections are ongoing themed collections highlighting the best past and present work in Dalton Transactions.

This collection demonstrates the amazing breadth of ground-breaking research being undertaken in the area of metallocycles and metallocages all over the world.

Metallocycles and metallocages are discrete, 2D and 3D metal-organic architectures. These beautiful and often complex structures can be formed from relatively simple building blocks through self-assembly processes centred around transition metal and lanthanide coordination chemistry. The diversity of accessible topologies and sizes, combined with their well-defined cavities, make them fascinating synthetic targets and attractive hosts in supramolecular chemistry. This Spotlight Collection aims to celebrate recent developments in the field, highlighting both fundamental and applied research.

Fundamental research into the construction and structural interconversion of new cages and metallocycles remains a valuable and popular research topic, while new and varied applications of these structures continue to develop and expand. Examples found within this collection include studies of spin and magnetism, hierarchical self-assembly into gels and applications in catalysis, separations, cancer therapeutics and optical detection.

This collection is guest edited by Dalton Transactions Advisory Board member Professor Lin Xu (East China Normal University), alongside Dr Cally Haynes (University College London) and Dr James Lewis (Imperial College London).

Dalton Transactions Outstanding Paper Award 2022

We are delighted to announce the winner of our 2022 Outstanding Paper Award.

The Outstanding Paper Award is a new award aimed at recognising the great work published in Dalton Transactions from the previous year. The process for selecting the winner involves the shortlisting of papers published in the journal within the previous year based on nominations by members of the Editorial Board as well as a variety of metrics including article downloads, Altmetric score and citations. The Editorial Board then votes on this shortlist to select the winner.

Conformationally dynamic copper coordination complexes

Bronte J. Charette, Paul J. Griffin, Claire M. Zimmerman and Lisa Olshansky*

Dalton Trans., 2022, 51, 6212-6219

In this outstanding article, the authors explored the interplay between molecular and electronic structure for a series of Cu(I) and Cu(II) complexes with dpaR ligands through various spectroscopic and physical techniques.

 

Meet the authors of this outstanding paper

Lisa Olshansky

Lisa Olshansky is an Assistant Professor of Chemistry at UIUC. She received her PhD from MIT in 2015. Her current research focuses on mimicking the ways that biological systems efficiently interconvert different forms of energy. Specifically, she hypothesizes that there is a critical interplay between macroscopic changes in molecular structure and subatomic changes in electronic structure that can be leveraged for diverse applications ranging from solar energy conversion to biomedical research. Olshansky has been named a Searle, Vallee, and Cottrell Scholar, a Kavli fellow (2022), and has received early career research awards from the NIH and DOE.

 
Bronte Charette

Bronte obtained her B.Sc. in Chemistry from the University of Winnipeg where she began her research career in synthetic inorganic chemistry which she continued during her M.Sc. studies under the supervision of Prof. Jamie Ritch at the University of Manitoba. In 2021, Bronte received her Ph.D. in Chemistry from the University of California, Irvine as a Natural Science and Engineering Research Council of Canada (NSERC) Postgraduate Doctoral Fellow with Prof. Alan Heyduk. Her postdoctoral work with Prof. Lisa Olshansky focused on synthesizing switchable transition metal complexes for renewable energy conversion strategies. Bronte is excited to start her independent career as an assistant professor at UC Davis this summer.

Paul Griffin

Paul Griffin received his bachelor’s in chemistry and philosophy (2016) and his Master’s in chemistry (2018) from the University of Scranton. His master’s research was conducted under Dr Art Catino in which he developed a general approach to synthesize substituted tetraarylmethanes. Paul recently obtained his PhD in inorganic chemistry at the University of Illinois, Urbana-Champaign (2023), where he works with Lisa Olshansky to study the relationship between conformational dynamics, photochemistry, and electron transfer in copper coordination complexes. Paul is passionate about mentoring the next generation of scientists and explores his philosophy interests by having riveting discussions with his cat, Mookie.

Claire Zimmerman

Claire completed her B.S. at the University of Illinois at Urbana-Champaign under Dr Lisa Olshansky. She is currently in her first year of graduate studies at the University of California Irvine with Dr Jenny Yang.
