Abstract

Arm wrestling: Backbone-directed "arm-to-arm" aggregation of a newly designed perylene bisimide (PBI) dyad with a defined intramolecular space leads to the growth of kinetically stable extended PBI π-stacks. This PBI dyad was shown to assemble into oligomers up to 21 units in length.

Keywords: dyes/pigments; kinetics; self-assembly; thermodynamics; π-stacking.
