Abstract

A convenient synthesis of a number of 3,3'-bridged-bis-2,2'-thienyls as potential building blocks for novel conducting polymers is reported. The UV-spectra and oxidation potentials of these novel compounds aregiven. Although the UV-spectra correlated to the degree of coplanarity of these species, the oxidation potentials did not correlate, and notendency to polymerize was observed for the N-bridged thienyls, 1a-1d, 2a-2c. This behavior is in contrast to results found for other 2,2'-bithienyls. These findings are explained by nitrogen and sulfur adsorption orientation of the N-bridged biethienyl molecules on the electrode surface prior to electron transfer.
