The Department of Chemistry is pleased to announce that the spring 2019 Rathore Lecture will be given by Sir Fraser Stoddart on April 12, 2019 at 4 pm in room 121 of the Todd Wehr Chemistry Building.
Sir Fraser Stoddart, 2016 Nobel Laureate in Chemistry, is presently a Board of Trustees Professor at Northwestern University. Stoddart has pioneered the development of the use of molecular recognition and self-assembly processes in template-directed protocols for the synthesis of mechanically interlocked molecules, such as catenanes and rotaxanes. He obtained all his degrees from Edinburgh University and has spent time at Queen’s University in Canada, Imperial Chemical Industries, the Universities of Sheffield and Birmingham in the UK and the University of California, Los Angeles. During the past five decades, Stoddart has mentored 500 graduate students and postdoctoral scholars from 50 different countries. He was made a Knight Bachelor by Her Majesty Queen Elizabeth II in 2007 for his services to chemistry and molecular nanotechnology. Stoddart is a Fellow of the Royal Society of London and an Honorary Fellow of the Royal Society of Chemistry. His many awards include the King Faisal International Prize in Science (2007), the Albert Einstein World Prize in Nanotechnology (2007), and the Royal Medal (2010). He is a Member of the American Academy of Arts and Sciences, the National Academy of Sciences, the EU Academy of Science and a Foreign Member of the Chinese Academy of Sciences.
Rajendra Rathore, Pfletschinger-Habermann Professor of Organic Chemistry at Marquette University, unexpectedly passed away on February 16, 2018, following a brief battle with respiratory disease. Dr. Rathore was a devoted husband and loving father to two daughters, and had a zeal for life that was embodied in his passion for his family, as well as for his science.
Professor Rathore received his M.Sc. in 1986 from the Indian Institute of Technology (IIT)-Kanpur and earned his Ph.D. in Organic Chemistry from the University of Western Ontario in London, Canada in 1990. He was a post-doctoral research associate (1992-1997) and a visiting assistant professor (1997-2000) at the University of Houston under the supervision of Dr. Jay K. Kochi. He joined the faculty at Marquette University in August 2000.
Dr. Rathore made key contributions to the areas of organic supramolecular and materials chemistry. He was particularly interested in the rational design and synthesis of novel electro-active molecules with applications in molecular recognition, photovoltaics, and molecular electronics. His recent work demonstrated that frontier molecular orbitals can be applied in the design and synthesis of novel electro-active species, akin to their well-known application in the rationalization of pericyclic reactions.
During Dr. Rathore’s incredibly distinguished career, he has published more than 150 articles in various respected journals, including Science, Journal of the American Chemical Society, and Angewandte Chemie. He has an h-index of 35, and his research papers have been cited more than 3,700 times. Dr. Rathore’s incredible passion for research and science will live on through the Raj Rathore Memorial Lecture and Memorial Scholarship.
Dr. Rathore's research was broadly defined as in the area of organic supramolecular and materials chemistry. He was interested in a variety of topics with a strong emphasis on the design and synthesis of novel electro-active molecules that can be utilized as practical molecular devices for the applications in the emerging field of nanotechnology as well as in biomaterial applications. Graduate and undergraduate student and postdoctoral researchers in his group were exposed to a broad range of topics including synthetic organic chemistry, organometallic chemistry, electrochemistry, photochemistry, time-resolved laser spectroscopy, and X-ray crystallography. The projects his group pursued were independent but highly interrelated and are best summarized as follows:
This research lies at the interface of synthetic organic chemistry, molecular recognition, material science, solid state electronics, and biology with the ultimate aim of studying and exploiting new organic molecules and materials that can be used as molecular devices, such as sensors, switches, wires, ferromagnets, semiconductors, and other electronic and optoelectronic devices. To fulfill this task, the group used intra- and inter-molecular interactions that are present in supramolecular and macrocyclic assemblies containing multiple redox-active chromophores for the construction of higher-order organic materials. Ultimately, a fundamental understanding of weak interactions among molecules and ions (i.e. molecular recognition) encompasses all of these issues, and has wide ranging implications from areas as diverse as molecular machines to solar energy storage.
As an example, the group showed that a systematic study of the interaction of cofacial receptors (in which the aryl moieties are oriented at varying angles) with gaseous nitric oxide (NO)-an important biological messenger, led to the development of remarkably efficient receptors for NO (KNO > 108 M-1). The group also exploited this remarkably efficient binding of NO with stilbenoid and calixarene receptors to develop functional molecular sensors for nitric oxide.
