Abstract

We apply excited state molecular dynamics to a set of substituted guanine-benzo[a]pyrene diol epoxide-cyano-based molecules with push-pull donor-acceptor behaviour. Changing the position of the cyano group tunes fluorescence and charge transfer properties of these systems. Our work provides new rational design principles for creating fluorescent nucleobase derivatives with desired properties.
