, p. 71 - 78 (2007/10/02)
The synthesis and electrochemical data of new donors - 4,4'-biselenopyranylidenes - are described.The optical and electrical properties of complexes with TCNQ and DDQ are mentioned.
SYNTHESE D'UNE NOUVELLE CLASSE DE DONNEURS: BIS(SELENOPYRANNYLIDENES)-4:4'(BSeP)
Es-Seddiki, Said,Coustumer, Gerard Le,Mollier, Yves
, p. 2771 - 2772 (2007/10/02)
We report here the first synthetic method to reach biselenopyranylidenes derivatives from either the selenopyrylium ions or the corresponding selenopyranethiones.TCNQ and DDQ complexes are described.
