A new class of push–pull molecules bearing γ-methylene chalcogenapyran and benzopyran nucleus as proaromatic donors and methoxypentacarbonyltungstene carbene fragment as acceptors is described. N.L.O. properties (as μβ by EFISH) of these complexes have been investigated. The influence of the unsaturated chain length, of the presence of the fused aromatic ring and of the chalcogen atom on the first hyperpolarizability values are shown.
N.L.O. properties of a new class of “push–pull” Fischer type carbene complexes bearing γ-methylene chalcogenapyran and benzopyran nucleus as proaromatic donors have been investigated. The influence of the unsaturated chain length, of the presence of the fused aromatic ring and of the chalcogen atom on the first hyperpolarizability values are shown.Figure optionsDownload as PowerPoint slide
