    Optimizing specific third-order polarizabilities and approaching the fundamental limit in donor substituted cyanoethynylethenes (CEE) molecules

  • Original language description

    We review the molecular third-order polarizability of a series of compact two-dimensional cyanoethynylethene derivatives and show that the best molecules have a nonlinearity that is only by a factor of 50 lower than the fundamental limit derived by Kuzyk, which is revealed to be a quite useful concept in discussing the observed trends in molecular nonlinearities. We also show that the nonlinearity of this family of molecules contains a large two-photon contribution, and that the best molecules have a very high specific third-order polarizability, meaning that they pack a large nonlinearity in a relatively small size.

    Optimalizace specifické polarizability třetího druhu a přiblížení se fundamentálními limitu pro donor substituované kyanoethynyletheny (CEE)

  • Czech description

    Byla vyšetřována polarizabilita třetího druhu pro sérii dvoudimenzionálních CEE, kdy nejleslibnější molekuly vykázaly nonlinearitu pouze 50-krát nižší než je fundamentální limit odvozen Kuzykem. Dále bylo ukázáno, že nonlinearita těchto látek je způsobena rovněž silným příspěvkem dvoufotonové absorpce. Nejlepší molekuly vykázaly velice vysokou specifickou polarizabilitu třetího druhu, kdy relativně malá molekula je nositelem značné nonlinearity.
