nanoCHAts: Informal conversations about teaching

A collection of all of the IONiC VIPEr NanoCHAts. These are short discussion on a teaching topic by 4-5 faculty members from different institutions. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.

Anion Coordination Chemistry (Bowman-James)

Ligands can bind to anions, just as they do to metal ions, and Bowman-James developed these analogies as well as many examples of selective anion binding ligands.  This short slide decks gives background to her work as well as some relevant introductory material.

Artificial Photosynthesis Using Quantum Dot / Porphyrin Aggregates (Weiss)

This literature discussion highlights recent research from the Weiss group in which electrostatically assembled aggregates of CuInS2 / ZnS quantum dots and trimethylamino-functionalized tetraphenylporphyrin molecules were used to selectively reduce carbon dioxide to carbon monoxide.

Proton-Assisted Reduction of CO2 by Cobalt Aminopyridine Macrocycles (Marinescu)

Various topics ranging from coordination chemistry, electrochemistry, solid state chemistry and point group and symmetry are discussed from the JACS article published by Smaranda C. Marinescu and her co-workers.  The article describes the conversion of CO2 to CO by using cobalt aminopyridine macrocycle catalysts.

Development of Expanded Porphyrins (Sessler)

The LO focuses upon classic articles describing the synthesis and characterization of the first "texaphyrin" compounds.

This LO is part of a special VIPEr collection honoring the 2021 ACS National Award recipients in the field of inorganic chemistry. Jonathan L. Sessler was the recipient of the Ronald Breslow Award for Achievement in Biomimetic Chemistry for the discovery of expanded porphyrins, molecular recognition via base-pairing, pyrrole-based anion binding, and demonstrating the power of this biomimetic chemistry in drug discovery.

The Organometallic Chemistry Behind the Polymer of Squares (Chirik)

The discussion covers a 2021 publication by the Chirik group (Nature Chemistry, 2021, DOI: 10.1038/s41557-020-00614-w) which details the discovery of a new way to polymerize butadiene through iron-catalyzed [2+2] cycloadd

5 slides about nomenclature

I have never enjoyed teaching nomenclature, but it is certainly important for students to know what is meant when they see a name out there in the wild. I use Gary's excellent in-class activity (linked below) and then follow up with these slides to cement the knowledge in the last 10-20 minutes of class. The first content slide is a list of nomenclature rules from IUPAC but I normally fill in a list of class-generated rules on the title slide before moving to the truth... our in-class rules are often quite close to the published rules.

Resolution of Werner complexes -- the COVID edition

This is a classic experiment that has been revised and updated numerous times over the years. The experiment can be found in Girolami, Rauchfuss and Angelici, 3rd edition, but that edition removed some purification steps that were present in the earlier edition which has plagued generations of my students with poor resolution of the enantiomers. Marion Cass published a J. Chem. Educ. article in 2015 that included a pH determination and added back in the recrystallization step. This allowed my students to achieve higher yields and greater resolution in Spring 2020.
