Abstract
We have prepared new organic anionic acceptors, Br2XQNHCH2SO3â (2: X=Br, 3: X=BryCl1ây (yâ0.5), 4: X=Cl; Q=1,4-benzoquinone), that possess both an electron acceptor part (1,4-benzoquinone) and an anionic part (sulfonate). The reduction potentials of the PPh4 salts of 2, 3 and 4 are â0.45, â0.45 and â0.46 V (vs. SCE in CH3CN), respectively. The results indicate that they are weaker acceptors than chloranil (â0.13 V) and bromanil (â0.12 V). Each anionic acceptor (AA) provided two BEDT-TTF salts, β-(ET)5(AA)2·DCE·zH2O and λ-(ET)2(AA)·CH3OH (AA=2, 3, or 4; z=2: 0.97, 3: 0.83 and 4: 0.40). The structures and transport properties of the salts are reported.
