Synthèse de chalcones à base de tétrathiafulvalène: RC(O)CHC(CH3)TTF, TTFC(O)CHC(CH3)R (R  TTF: C6H3S4; Bct: C6H5Cr(CO)3; Fc: C5H4FeC5H5). Propriété conductrice d'un nouveau complexe de transferst de charge TTFC(O)CHC(CH3)TTF · TCNQ

Abstract Novel chalcones that contain tetrathiafulvalene (TTF) and/or metallocene (ferrocenyl or benchrotrenyl) moieties: RC(O)CHC(CH 3 )R′ (R and/or R′  TTF: C 6 H 3 S 4 ; Fc: C 5 H 4 FeC 5 H 5 ; Bct: C 6 H 5 Cr(CO) 3 ) were prepared using TiCl 3 /Et 3 N as the condensation reagent. The 1-1 charge transfer complex with TCNQ (tetracyanoquinodimethane was obtained for the ditetrathiafulvalenic derivative (R  R′ TTF). This complex exhibits the semiconducting behaviour.
