title: Syntheses and properties of the new electron transfer sensitizers 4,2'-pyrylogens.
abstract: The syntheses and characterizations of the 4,2'-regioisomers of the dicationic pyrylogen electron transfer sensitizers are reported. The electrochemical and photophysical properties of these sensitizers are compared to the previously reported 4,4'-pyrylogens.
