Introduction to Photoinduced Electron Transfer

Five Slides About

Submitted by Robert Holbrook, Northwestern University
Categories
Description: 

This 5 slides about will introduce students to the concept of photoinduced electron transfer. These slides go over the energics of photoinduced electron transfer, which implements basic concepts of photochemistry and electrochemistry. The photoinduced electron transer properties of ris-(2,2'-bipyridine)-ruthenium(II) is used as an example.

Learning Goals: 

Students will be introduced to photoinduced electron transfer and how to determine the driving force between an electron acceptor/donor pair. Students will be able to incororapte photochemistry and electrochemistry to inorganic complexes. Tris-(2,2'-bipyridine)-ruthenium(II) is used as an example. Students should learn the basic concept of photoinduced electron transfer and how to determine the thermodynmics for determining the driving force for PET. This maybe an interesting way to merge concepts of photochemistry and electrochemistry. The excited state of a molecule effects its reduction potentials dramatically (a 2.12 V shift in reduction potential for Ru(bpy)3). This concept is used in a wide variety of research topics from dye-sensitized solar cells to electron transfer in photosystem II.

Implementation Notes: 

These slides can be used in a lecture or a reference to introduce the concept of photoinduced electron transfer. Students must have had an introduction to basics of photochemistry and electrochemistry prior to these notes.
