Contraction And Expansion

The application of 3,3'-diphenyl-2'2-bithiophene as a helical scaffold capable of electrochemical polymerization to yield the corresponding polythiophene is reported. One unique feature of this monomer is its theoretically predicted (DFT) ability to mimic redox-stimulated contraction and expansion. This ability, coupled with traditional electromechanical actuation properties of bulk, redox-active conjugated polymers (CPs), yields a polymeric "molecular muscle" capable of both contraction and expansion.

Redox Behavior

Control over the electronic structure in π-conjugated polymers is of great importance for the development of organic electronics and spintronics. In this study, we synthesized a sheathed cross-conjugated polythiophene through oxidative electrochemical polymerization. Spectroelectrochemistry has revealed that unlike linearly conjugated polythiophenes, polarons were confined in the repeating units that were segmented by cross-conjugation.

Nanotubes and nanowires of π-conjugated polypyrrole (PPy) and poly (3,4-ethylenedioxythiophene) were synthesized using Al 2 O 3 nanoporous template through electrochemical polymerization method. From the SEM and TEM photographs, the formation of conducting polymer nanotube (CPNT) and nanowire (CPNW) was confirmed. From FT-IR and UV/Vis absorbance spectra, we observed the effect of doping and de-doping through HF or NaOH dissolving of Al 2 O 3 template. DC conductivity and I–V characteristics as a function of temperature and gate bias were measured for the CPNTs and CPNWs prepared with various synthetic conditions. Magnetic properties were measured through EPR experiments. Based on the results, we compare the intrinsic properties between bulk and nanoscale π-conjugated polymers.
