Abstract
AbstractWe used a helical polymer backbone (polyacrylamide) as a scaffold to organize perylene diimide chromophores into well‐defined foldamers, which further undergo self‐assembly into supramolecular tube‐like arrays in aqueous media, as revealed by cryo‐TEM imaging. The arrays are supramolecular polymers, whose structure is templated by folded primary building blocks, representing a useful tool for directing self‐assembly . Exciton migration in the supramolecular arrays was studied by transient absorption and revealed a moderate exciton diffusion propensity.
