Quadruple π stack of two perylene bisimide tweezers: a bimolecular complex with kinetic stability

Changzhun Shao et al. Angew Chem Int Ed Engl. .

Abstract

Self-assembly: A tweezer-type perylene bisimide (PBI) dyad self-assembles into a defined bimolecular complex composed of a quadruple PBI π stack with remarkable kinetic stability, which is unprecedented for π-stacked dye aggregates (see picture). These persistent supramolecular species are of considerable interest for the elucidation of functional properties of dye aggregates.

Keywords: dyes/pigments; kinetic trapping; self-assembly; tweezers; π stacks.
