DNA is one of the best candidates as building blocks for bottom-up approach to nanometer size architecture in nanotechnology. In natural photosynthetic system, the arrangement of porphyrin derivative with regulated distances, orders and orientations provide an efficient photon-energy collecting and transmittion. Sequential arrangement of chromophore (dye molecule) should therefore be a good model of artificial photosynthetic and photo-energy transmission systems. Sequential arrangements of three kinds of chromophores separated by regulated distances equaling approximately one pitch of the DNA duplex (3.4 nm) in non-covalent molecular assembly systems are constructed using chromophore/oligo-DNA conjugates. Vectorial photo-energy transmission along the DNA helix axis by fluorescence resonance energy transfer (FRET) in a sequential chromophore array was observed by fluorescence spectra measurements and analyzed by time-resolved fluorescence spectroscopy measurements using a femtosecond pulse laser system.
