Dimers 3, 4 and 7 which consist of two reducible pentakis(thiophenyl)benzene subunits linked by different molecular structures, have been synthesised as model compounds for reducible molecular-wire-type synthons to represent differences in the electron-transfer ability as a function of the bridging structure. The bridging units consist of para-divinylbenzene in 3, bis-hydrazone in 4 and diacetylene in 7. Their ability to transfer electrons from one reducible subunit to the other was investigated by electrochemical and spectroelectrochemical methods and, in the case of 4 and 7 the solid-state structures support the experimental findings. The para-divinylbenzene bridge in 3 was found to completely isolate the reducible structures (Class I system). In contrast, the diacetylene bridge in 7 electronically connects the two reducible structures (ClassIII system) and, thus, demonstrates its potential application as a "molecular wire" The bis-hydrazone-linked compound 4 displayed only a low level of electronic connection between the subunits and was only observed in the spectroelectrochemical investigation.
