Electron transfer dithiolene-donor complexes

Metal dithiolene complexes such as [M(mnt)2] and [M(dmit)2] (see Chart 3) are electron-transfer active and can be readily generated in oxidized or reduced forms with variable charge z and can be used as either donors or acceptors. 

The precursor dithiocarbonates were also used to prepare mesomorphic derivatives of TTF (tetrathiafulvalene), a strong electron donor compound used in the formation of highly conductive charge transfer complexes. Attempts to prepare CT complexes between the mesomorphic dithiolenes as acceptors and these mesomorphic TTF donors showed that the electron acceptor strength of this type of dithiolene does not suffice to form strong donor-acceptor complexes mixtures of the two components form mixed crystals without any visible degree of charge transfer.208...
