This 5 slides about outlines the basics of lanthanide photophysics as a primer for those new to the topic. These properties are very unique and actually very useful, which is a topic for another time. The intricacies of what causes the Ln luminescence, its strengths and drawbacks are discussed along with how these drawbacks are addressed in molecular complexes. Notes for the instructor are included that explain each slide.
The colors of transition metal compounds are highly variable. Aqueous solutions of nickel are green, of copper are blue, and of vanadium can range from yellow to blue to green to violet. What is the origin of these colors? A simple geometrical model known as crystal field theory can be used to differentiate the 5 d orbitals in energy. When an electron in a low-lying orbital interacts with visible light, the electron can be promoted to a higher-lying orbital with the absorption of a photon. Our brains perceive this as color.
ColourLex (colourlex.com) is an amazing website that mixes chemistry and art. The creators of this website have extensively catalogued paintings and the pigments that were used to create them. The pigments range from artificial to natural and organic to inorganic. You can search for the specific combination that you want to see.
The following is a simple in-class “demonstration” that I use to segue between d to d and charge transfer transitions. After teaching about d to d transitions and Tanabe-Sugano Diagrams, I show my students three solutions that I have put in large test tubes before class. The three solutions I place in the test tubes are:
a. 10 ml of 0.1M Co(H2O)62+
b. 10 ml of 0.1M Cu(H2O)62+
c. 10 ml of a freshly prepared 0.1 M KMnO4 solution
This learning object is based on discussion of the literature, but it follows a paper through the peer review process. Students first read the original submitted draft of a paper to ChemComm that looks at photochemical reduction of methyl viologen using CdSe quantum dots. There are several important themes relating to solar energy storage and the techniques discussed, UV/vis, SEM, TEM, electrochemistry, and catalysis, can be used for students in inorganic chemistry.
This is a resource that has short, animated tutorials on a variety of different topics. Most of the topics are materials science and/or engineering topics but there are several that would be of interest to chemistry students. (A full list of topics is given below.)
The resources on this website will help students learn concepts in materials chemistry, solid state chemistry, and nanoscience. The website provides links to
In the 2013 Inorganic Curriculum Survey, respondents were asked about the resources they used when they teach inorganic chemistry. About 20% of respondents selected "other" and provided information about these resources. A number of people mentioned specific websites. This collection consists of the websites submitted in the survey.
A series of JAVA applets of Tanbe-Sugano diagrams were developed by Prof. Robert Lancashire at the University of the West Indies. These diagrams allow students to determine deltao/B values based on ratios of peak energies without the pain of rulers and drawing lines. There are also features that allow a person to input values and automatically calculate certain parameters. You can also quickly find values of delta_o and B for certain complexes via a drop-down menu on some of the pages (e.g. Cr3+ complexes).
