DNA-templated control of chirality and efficient energy transport in supramolecular DNA architectures with aggregation-induced emission.

ABSTRACT: Two conjugates of tetraphenylethylene with d-2'-deoxyuridine (1d) and l-2'-deoxyuridine (1l) were synthesized to construct new supramolecular DNA-architectures by self-assembly. The non-templated assemblies of 1d and 1l show strong aggregation-induced emission and their chirality is exclusively controlled by the configuration of their sugar part. In contrast, the chirality of the DNA-templated assemblies is governed by the configuration of the DNA, and there is no configuration-selective binding of 1d to d-A₂₀ and 1l to l-A₂₀. The quantum yield of the assembly of 1d along the single-stranded DNA A₂₀ is 0.40; approximately every second available binding site on the DNA template is occupied by 1d. The st
