DNA-based molecular wires: Multiple emission pathways of individual constructs

Article Abstract:

A single-molecule spectroscopy (SMS) with pulse interleaved exciting imaging is used for an exhaustive study of the extent of photon energy transfer through individual DNA-based molecular wires comprised of five dyes, resolving the time evolution spectral response of individual constructs and simultaneously probing DNA integrity. The observations exhibit the dynamical and multiple pathways for photon emission, a phenomenon that mostly leads from conformational freedom of the wire and partial DNA hybridization on these complex systems.

Charge transfer absorption for [pi]-conjugated polymers and oligomers mixed with electron acceptors

Article Abstract:

Charge transfer (CT) absorption bands of ground state complexes are identified for [pi]-conjugated polymers and oligomers with electron acceptors in chloroform solution. The spectral position of CT bands was found to correlate with the electrochemical oxidation potential of the [pi]-conjugated donor and the reduction potential of the acceptor.
