Silanediol-Bay-Bridge Rigidified Axially Chiral Perylene Bisimide

Chiral organic molecules with a complementing π-structure are highly desired to obtain materials with good semiconducting properties and pronounced chirality effects in the visible region. Herein, we introduce a novel design strategy to achieve an axially chiral and rigid perylene bisimide (PBI) dye by attaching the chirality-inducing 2,2'-biphenoxy moiety at one side of the bay area and the rigidity-inducing di-
