Artificial Photosynthesis Using Quantum Dot / Porphyrin Aggregates (Weiss)

Submitted by Anne Bentley / Lewis & Clark College on Sun, 03/28/2021 - 14:17
Description

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.

SLiThEr #18 - March 25th at 3 pm EDT

Submitted by Matt Cranswick / Oregon State University on Fri, 03/19/2021 - 14:45

There was a professor at Lafayette
Who decried in an apoplectic fit:
A publisher’s book,
Where will I look?
And has since succumbed to LibreText

Please join us for the penultimate SLiThEr of the semester by Chip Nataro, in which he will talk about his rapid adoption of a LibreText for the spring semester. We ask that you sign-up in advance here.

 

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

Submitted by Todsapon T. / University of Evansville on Sun, 03/14/2021 - 15:32
Description

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.

Terminal Uranium (VI) Nitrides: Photoredox Synthesis and Reactivity (Mazzanti)

Submitted by Hilary Eppley / DePauw University on Tue, 03/02/2021 - 12:31
Description

This is one of a collection of learning objects developed to honor the 2021 ACS Award Winners in inorganic chemistry.  Marinella Mazzanti from the Swiss Federal Institute of Technology was awarded the F. Albert Cotton Award in Synthetic Inorganic Chemistry for her outstanding accomplishments in uranium and lanthanide chemistry, including the stabilization of unusual oxidation states and multimetallic cluster synthesis and small-molecule activation. In this paper photoredox chemistry is used to synthesize a uranium (VI) nitride.

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.

The Organometallic Chemistry Behind the Polymer of Squares (Chirik)

Submitted by Megan Mohadjer Beromi / United States Naval Academy on Sat, 02/20/2021 - 12:34
Description

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

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.

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.
