Tetraphenylethylene-DNA conjugates: influence of sticky ends and DNA sequence length on the supramolecular assembly of AIE-active vesicles

Org Biomol Chem. 2022 May 11;20(18):3703-3707. doi: 10.1039/d2ob00357k.

Abstract

The supramolecular assembly of DNA conjugates, functionalized with tetraphenylethylene (TPE) sticky ends, into vesicular structures is described. The aggregation-induced emission (AIE) active TPE units allow monitoring the assembly process by fluorescence spectroscopy. The number of TPE modifications in the overhangs of the conjugates influences the supramolecular assembly behavior. A minimum of two TPE residues on each end are required to ensure a well-defined assembly process. The design of the presented DNA-based nanostructures offers tailored functionalization with applications in DNA nanotechnology.
