Advances in Metallacrown Chemistry

ISBN-13: 9783031085758 / Angielski / Twarda / 2022

Opis

This volume focuses on recent developments in metallacrown chemistry. While the field was established in 1989 by Professor Vincent Pecoraro and numerous applications had been proposed, there has been a recent surge in the practical applications for this class of molecules. Written by leaders in the metallacrown chemistry field this book addresses recent developments. The single-molecule magnet properties of metallacrowns are presented along with discussions on their ability to bind DNA, as well as their potency to serve as building blocks for supramolecular structures. The volume is not only intended for those who work directly in the field of metallacrowns but it also appeals to those working in the aligned fields of metallamacrocyclic chemistry, self-assembly chemistry, and supramolecular chemistry. This dedicated volume serves as an encyclopedic reference for those wishing to gain insight into the field.

O autorze

Curtis Zaleski earned his Bachelor of Science degree in chemistry at John Carroll University in Cleveland, Ohio while working with Professor Paul R. Challen.  He then earned his Ph.D. degree in chemistry at the University of Michigan in Ann Arbor, Michigan under the mentorship of Professor Vincent L. Pecoraro.  His doctorate research focused on the single-molecule magnetic properties of metallacrowns.  In addition, he was involved with the Preparing Future Faculty program in the Department of Chemistry under the direction of Professor Brian P. Coppola.  Upon earning his degree, he continued under Dr. Pecoraro’s mentorship for a teaching-research postdoctoral fellowship that allowed him to hone his teaching skills and prepare for an academic role at a primarily undergraduate institution.  In 2006 he joined the Department of Chemistry and Biochemistry at Shippensburg University in Shippensburg, Pennsylvania as an Assistant Professor, rose to Associate Professor in 2011, and was promoted to Professor of Inorganic Chemistry in 2016.  While at Shippensburg University he has had the privilege to mentor over 40 undergraduate students in research and publish numerous articles with them.  The research of the group focuses on the synthesis and magnetic characterization of lanthanide-containing metallacrowns in particular heterotrimetallic systems with either manganese or aluminum ions in the ring positions of the molecules.
