title = "Theoretical design of substituted tetrathia-[7]-helicenes with large second-order nonlinear optical responses",
abstract = "Increasing response: Semiempirical calculations show that substituting tetrathia-[7]-helicene in positions 7 and 8 (see graphic) as well as in positions 2 and 13 by adequate donor/acceptor pairs can lead to a substantial increase of the second-order nonlinear optical response.",
