A series of new metal (M) dithiolene complexes bearing terthiophene (3, 12, M = Ni; 4, M = Pd; 5,
6, M = Au) and 2,5-bis(para-methoxyphenyl)thiophene units (14, M = Ni; 15, 16, M = Au; 17, M =
Pd) have been synthesised in 38–99% yield. The electrochemical properties of the materials have been
characterised by cyclic voltammetry and UV-vis spectroelectrochemistry. The nickel complexes possess
low oxidation potentials (−0.12 to −0.25 V vs Ag/AgCl) due to the electron-rich dithiolene centres and
all complexes display ligand-based redox activity. The terthiophene derivatives have been polymerised
by electrochemical oxidation to give stable films with, in the case of poly(3), broad absorption
characteristics. Charge transfer materials have been isolated from 14 and 16 with conductivities in the
range 9 × 10−6 to 7 × 10−8 S cm−1.
