Abstract

original image

Control by conformation: The photophysical interactions and energy transfer between the covalently attached chromophores ethynyl pyrene (Py) and ethynyl nile red (Nr) can be much better realized when modulated with the sterically constrained pyrrolidinyl PNA (shown in green) than with pure DNA.
