• rotation and therefore isomerisation. It can be anticipated that the two isomers will not differ significantly in their electrochemical properties (see below). Compound 3 was trans-chalcogenated by mercury(II)acetate in a mixture of acetic acid and CH2Cl2 to give the oxo derivative 26 in 89% yield

• monomers are very similar, the optical and electrochemical properties of the two isomeric polymers are quite different. Suzuki coupling of M-2 and a fluorene diboron ester derivative resulted in polymer P-21 with fully conjugated main chain, the absorption being shifted by 15–25 nm compared with the

• [(1,3-dithiol-2-ylidene)alkyl]ferrocenes (2) was shown to form 1:1 CT complexes with tetracyano-p-quinodimethane (TCNQ, 3) and dichlorodicyanoquinone (DDQ) 4, see Figure 1 [24][25][26]. Subsequently, a number of reports have appeared dealing with the electrochemical properties of these CT complexes of

• tetrathiafulvalenes having a ferrocene moiety [10][11]. These findings prompted us to synthesize and investigate the electrochemical properties of symmetrical 1,1′-bis[(1,3-dithiol-2-ylidene)heteroaryl/aryl]ferrocenes substituted with heterocyclic and aromatic ring moieties separated by ferrocene moiety as the
