Abstract

Abstract Novel bay-functionalized perylene diimides with additional substitution sites close to the perylene core have been prepared by the reaction between 1, 7 (6)-dibromoperylene diimide 6 (dibromo-PDI) and 2-(benzyloxymethyl) pyrrolidine 5. Distinct differences in the chemical behaviors of the 1, 7-and 1, 6-regioisomers have been discerned. While the 1, 6- dibromo-PDI produced the corresponding 1, 6-bis-substituted derivative more efficiently, ...
