My Notes

This literature discussion on the Hot Paper communication in Chemistry, A European Journal; highlights the first examples of borepinium and borfluorenium cations whose optical properties can be tuned and also the very first reported example of thermochromism in these cationic species. R. J. Gilliard, Chem. Eur. J. 2019, 25, 12512.

This assignment provides a demonstration of structure-function relationships in the context of a main group system. Students critically read and analyze a short communication paper and relate a challenging research report to fundamental chemistry principles.

Robert J. Gilliard, Jr. is a chemist and researcher who is the Novartis Associate Professor of Chemistry at Massachusetts Institute of Technology. He was one of C&EN’s Talented 12 in 2020, in which they highlight a dozen young rising stars who are using chemical know-how to change the world. He was awarded the 2023 Harry Gray Award for Creative Work in Inorganic Chemistry by a Young Investigator, sponsored by the Gray Award Endowment and administered by the American Chemical Society. 

Learning Goals

Students should be able to describe the chemistry of boron, relate ligand type to chemical/physical properties, and relate chemistry of boron compounds to fundamental principles of thermodynamics, bonding, and spectroscopy.

Implementation Notes

This literature discussion is yet to be implemented. One recommendation is to have the students read the communication for homework. They could then break into groups in class to answer the questions.    

Time Required
One class period
Evaluation Methods

Grading the group of students based on their answers.
