The oligothiophene compounds T 3 –T 7 inclusive have been synthesized by standard chemical procedures in order to measure the complex admittance versus frequency of their micro-crystalline powders as compressed into a co-axial tube capacitor. The results are compared to that obtained from commercially available polythiophene powder. Optical measurements of the UV–visible absorption...
A number of terthiophene derivatives have been synthesized by standard chemical procedures in order to measure the electrical properties of their micro-crystalline powders by impedance spectroscopy, in this case the complex admittance versus frequency. The compounds studied were T 3 , BrT 3 , Br 2 T 3 , T 3 NO 2 , BrT 3 NO 2 , IT ...
