Perylene Bisimide Atropisomers:  Synthesis, Resolution, and Stereochemical Assignment

, 2016
The macrocyclization of the tetra-hydroxyphenoxy-substituted perylene bisimide 4 bearing two (R)-configured 2-octyl substituents in the imide positions by etherification with diethylene glycol ditosylate afforded both the diagonally bridged (1,7- and 6 ...

Metal-free Annulation at the Ortho- and Bay-Positions of Perylene Bisimide Leading to Lateral π‑Extension with Strong NIR Absorption

, 2018
A novel ortho/bay annulation reaction of perylene bisimide (PBI) has been explored in a single step synthetic procedure using perylene bisimide 1 and 1,8-Diazabicyclo[5.4.0]­undec-7-ene (DBU) in the absence of any metal catalyst. The single crystal solid-
