Computational and cyclic voltammetry studies have been used to explore electrochemical reductions of three helically chiral homologues, 22+, 32+, and 42+, of methyl viologen. Thermochemical-electrochemical cycles are used as frameworks to describe th

Synthesis of three [4]heli-viologens and their helical precursors, and two “pseudo-[4]helicenes” and their alkylated derivatives, which have potential device and catalysis applications, are reported. Their structures and racemization barriers hav

The regiochemistry of four bis-Mallory photocyclization substrates has been examined from experimental and computational perspectives. Formation of all three possible regioisomers was only observed in the reaction of one of the substrates. In the oth

The first examples of chiral helical viologens are reported. These novel compounds have sufficiently long singlet lifetimes to support bimolecular photochemical reactions. They are quenched with di...

Several new dicationic viologen sensitizers are synthesized and characterized both photo- and electro-chemically. Benzo-annulation of methyl viologen increases its fluorescence lifetime by a factor of 6.6. Similar lifetime increases were observed for

A physical organic analysis of a collection of 57 data sets generated by B3LYP/6-311+G(2d,p) geometry optimizations and TD-DFT calculations is presented. The analysis engenders recommendations for syntheses of new pyrylogen electron-transfer sensitiz

The first helical viologen (4,4'-bipyridinium salt) has been prepared and characterized. Its reduction to the radical cation at -0.22 V vs SCE makes it the most easily reduced redox-active helicene known. It exhibits absorption at 397 nm for the S1

Practical aspects of setting up and running successful singlet-oxygen reactions with organic and organometallic substrates are discussed. Experimental factors that limit the lifetime of singlet oxygen and decrease its reaction efficiency, are examine
