Construction of DNA-templated one-dimensional assembly from acene molecules and the investigation of their opt-electronic properties

We report optical properties of one-dimensional anthracene stacks formed from single-component self-assembly of thymidylic acid-appended anthracene TACT and the binary self-assembly of TACT and complementary 20-meric oligoadenylic acid (TACT/dA20) in an aqueous buffer. Time-resolved fluorescence spectra for TACT suggested that the anthracene moieties in single-component assembly from TACT were flexible. Whereas the template-DNA molecule position the anthracene moieties at the center of a one-dimensional assembly, keep them at distances that permit Förster resonance energy transfer, and separate them from the solvent water molecules, which attack fluorescent molecules and cause non-radiative processes. As a result, the columnar anthracene stacks formed from the DNA-templated self-assembly of TACT can act as an energy transfer pathway in aqueous solution.
