Development of Expanded Porphyrins (Sessler)

Submitted by Shirley Lin / United States Naval Academy on Wed, 02/24/2021 - 09:24
Description

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.

5 slides about nomenclature

Submitted by Adam Johnson / Harvey Mudd College on Mon, 02/08/2021 - 18:11
Description

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.

metal acac complexes the COVID 19 version

Submitted by Adam Johnson / Harvey Mudd College on Mon, 01/18/2021 - 16:56
Description

For our virtual offering of inorganic chemistry laboratory at Harvey Mudd College in Spring 2021, I made some videos and collected some high quality data (IR, 1H NMR, MS, UV-Vis, mp, and X-ray diffraction) that I will make available for my students. The videos show the synthesis of Co and Mn acacs, the difference between as-prepared and recrystallized compounds, making solutions for UV-Vis and Evans method NMR, and making Evans method capillary tubes. The procedures for the synthesis of these compounds is found in Woolins (either the first or second editions). 

Linkage Photoisomerization of SO2 Bound to Osmium

Submitted by Nicole Crowder / University of Mary Washington on Thu, 01/07/2021 - 16:34
Description

In this literature discussion, students are asked to explore the chemistry behind a eta-1 to eta-2 linkage photoisomer of sulfur dioxide bound to pentammine osmium. There are questions that tie to chemical structure and the nature of the two bonding modes of the ligand as well as an examination of the spectroscopic properties of the complex in the solid state. Two of the questions ask students to draw some conclusions based on their knowledge of periodic trends and the sigma donor ability of ligands.

Introduction to batteries

Submitted by Abby O'Connor / The College of New Jersey on Thu, 01/07/2021 - 13:56
Description

A little more than 5 slides.... but hey batteries are important! Often there are not good slides available to introduce batteries, broadly, so I went a made them! These slides were also created to accompany the LO on redox flow batteries. This set of slides reviews alkaline batteries introduced in general chemistry and transitions to more modern approaches to batteries including lithium ion batteries and redox flow batteries. This work highlights the 2019 Nobel Prize work for lithium ion batteries.

Green Chemistry and Redox Flow Batteries

Submitted by Abby O'Connor / The College of New Jersey on Thu, 01/07/2021 - 10:56
Description

This paper in Chemical Science written by Ellen Matson and co-workers describes a structure function approach to improving the properties of non-aqueous redox flow batteries based upon polyoxovanadate-alkoxides (POV-alkoxides). Given the importance of battery technology on society and sustainable chemistry, this article allows students to engage with a paper that could have broad implications in society.

SLiThEr #13: Making Chemistry Worthwhile for the Non-Chemist

Submitted by Kari Stone / Lewis University on Thu, 12/31/2020 - 12:21
Description

This is the link to the 13th SLiThEr (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable), presented by Meghan Porter and Hosted by Chip Nataro. The SLiThEr was recorded and posted on YouTube (see the web resources link).

This particular roundtable focused on a reimagination of chemistry lab courses in the Age Of COVID and how to make chemistry relevant to non-chemists.
