Název v původním jazyce

Structure-Property Relationships and Nonlinear Optical Effects in Donor-Substituted Dicyanopyrazine-Derived Push-Pull Chromophores with Enlarged and Varied pi-Linkers

Popis výsledku v původním jazyce

Thirteen new, stable, push-pull systems featuring dimethylamino and pyrazine-2,3-dicarbonitrile moieties as the donor and acceptor, respectively, and systematically extended and varied pi-linkers were prepared and investigated. Evaluation of the measuredUV/Vis spectra, electrochemical data (cyclic voltammetry, rotating disc voltammetry, and polarography), X-ray data, and experimentally determined and calculated hyperpolarizability values enabled structure-property studies; these revealed some importantstructural features that affected the efficiency of intramolecular charge-transfer and nonlinear optical properties in this class of heterocyclic push-pull chromophores. The charge-transfer transition was most significantly affected by structural features such as pi-linker length, chromophore planarity, and the number of 1,4-phenylene/ethynylene subunits in the pi-linker.
