Title: Pyridinium Salts as Photoinduced Electron Traps
Biography

Abstract
When two or more Pyridinium salts are held face-to-face to each other they will share electrons equally between the rings. Calculations show this distribution of the trapped electron for the dimethyl 1,2-(di-4-pyridinium) ethane and the tetramethyl 1,1,2,2-(tetra-4-pyridinium) ethane as shown below. The electron trapping properties as characterized in ultrafast transient absorption spectroscopy and theoretical calculations for a variety of polypyridinium salts will be discussed.
