“…They contradict the expected results from the existing electrochemical models because slower oxidation rates were attained from deeper reduced initial states . Those unusual electrochemical responses were attributed to structural memory effects, relaxation processes,,, hysteresis effects,, or first cycle effect,, being considered as “anomalous” electrochemical responses ,,,. Similar singular electrochemical responses were also attained from carbon nanotubes, graphenes, or bipyridyl bilayers .…”

Each constitutive chain of a conducting polymer electrode acts as a reversible multi-step electrochemical molecular motor: reversible reactions drive reversible conformational movements of the chain. The reaction-driven cooperative actuation of those molecular machines generates, or destroys, inside the film the free volume required to lodge/expel balancing counterions and solvent: reactions drive reversible film volume variations, which basic structural components are here identified and quantified from electrochemical responses. The content of the reactive dense gel (chemical molecular machines, ions and water) mimics that of the intracellular matrix in living functional cells. Reaction-driven properties (composition-dependent properties) and devices replicate biological functions and organs. An emerging technological world of soft, wet, reaction-driven, multifunctional and biomimetic devices and the concomitant zoomorphic or anthropomorphic robots is presented.

“…The first approach involves the synthesis of conventional, random copolymers having pendant electroactive groups followed by their solution electropolymerization in the presence of the same or a different electroactive group 17–19. The second approach involves the simultaneous electropolymerization of different electroactive monomers from solution 20, 21. Third, transition metal catalyzed couplings and Grignard metathesis have also been used for polymerizations 22.…”

Herein, we report the synthesis of conducting poly (terthiophene)s using a side chain precursor polymer approach. Random copolymers were prepared by ring opening metathesis polymerization of two norbornylene monomers, one containing a pendant terthiophene group and the other containing a pendant acetate group. Solid‐state oxidative conversion of the terthiophene units was used to produce conductive polymers. Oxidative solid‐state conversion was successful for copolymers containing as little as 1 mol % of terthiophene comonomer. The electrical and optical properties of CPs were studied as a function of the amount of electroactive moiety, terthiophene (3T), present in the copolymer. The CPs were found to have conductivity varying between 10−1 and 10−4 S/cm depending on the precursor copolymer compositions. The CPs obtained from all precursors had no significant difference in their energy gaps and showed blue to orange color transitions when switching from the oxidized to the neutral states, respectively. The absorbance intensity at 426 nm for poly(3T) from the precursors fits the Beer–Lambert law corresponding to the range of initial 3T content in the precursor copolymer composition (from 1 to 100 mol %). © 2010 Wiley Periodicals, Inc.
