  Synthetic Procedure for Various Selenium-Containing Electron Donors of the Bis(Ethylenedithio)tetrathiafulvalene (BEDT-TTF) Type

  摘要：

  Six selenium variants of BEDT-TTF have been successfully synthesized by a newly developed synthetic method that involves a combination of two key reactions for the construction of two kinds of heterocyclic rings: the first is a one-pot formation of 1,3-dichalcogenole-2-chalcogenones from a common starting material, THP-protected 2-(ethynylthio)ethanol, leading to the inner five-membered rings, and the other is the annelation of the outer six-membered heterocyclic ring onto the inner ring by an intramolecular transalkylation reaction on a chalcogen atom. This method turned out to be widely applicable to the syntheses of the electron donors of bis(ethylenedithio)- and bis(ethyleneselenothio)-substituted types. However, synthetic attempts to form analogous donors of the bis(ethylenediseleno)-substituted type from THP-protected 2-(ethynylseleno)ethanol were unsuccessful. This is attributable to the predominance of side-reactions via a seleniranium (episelenonium) salt over the desired six-membered ring formation by transalkylation via a seleninium salt.

  The synthesis of a series of push-pull systems [donor (D)–acceptor (A)], associating the 1,3-dithiol-2-ylidene moiety (D) to various (A) fragments through polyolefinic linkages of various lengths, is described. Design optimization of these NLO phores isvia systematic determination of the molecular first hyperpolarizabilities beta; by the EFISH method. Selected compounds of this series, displaying the highest beta; values, are then chemically functionalized in order to promote their covalent grafting to polymeric backbones.
