“…Furthermore, considerable attention has been focused on the copolymers, due to their amazing electrical, physical, and electrochemical characteristics [28][29][30][31][32][33][34][35]. Recently, chemical copolymerization of formyl pyrrole (FPy) and pyrrole (Py) using acidic catalysts in the copolymerization was reported [36][37][38].…”

“…Another example is the electrochemical oxidation of Py in the presence of 22 [ 38 ]. Such a co-monomer structure results in cross-linked copolymer architecture, leading to polyether/polypyrrole cages.…”

Polypyrrole is a classical, well-known conjugated polymer that is produced from a simple heterocyclic system. Numerous pyrrole derivatives exhibit biological activity, and the repeat unit is a common building block present in the chemical structure of many polymeric materials, finding wide application, primarily in optoelectronics and sensing. In this work, we focus on the variety of copolymers and their material properties that can be produced electrochemically, even though all these systems are obtained from mixtures of the “simple” pyrrole monomer and its derivatives with different conjugated and non-conjugated species.

“…This was done by Massoumi et al who copolymerized pyrrole with N-ethyl, N-butyl, and N-octyl pyrrole with various monomer ratios and demonstrated that the conductivity of the copolymers was inversely correlated with the alkyl chain length due to more or less planar structure [14]. Similarly, Cihaner et al electro-oxidized a solution containing pyrrole and monomers with two pyrrolyl groups linked by a polyether spacer [15,16]. This oxidation led to the formation of N-substituted polyethereal polypyrrole films whose conductivity increased when the portion of pyrrole in the comonomer mixture was increased.…”

Conducting copolymer films were prepared from pyrrole (Py) and 1,12-di-(1-pyrrolyl) dodecane (DiPy) in an attempt to prepare conducting films that can be used as sensitive material of chemiresistor gas sensors. Copolymer thin films were obtained by electrochemical oxidation in a lithium perchlorate/acetonitrile electrolyte with different feed ratios of comonomers. Increasing the portion of DiPy in the comonomer mixture resulted in the formation of thinner and less rough copolymer films and to a modification of their morphology from a granular structure to a clover-like structure. In addition, copolymer films with very different conductivities were obtained by varying the comonomers ratio. Indeed, the conductivity of the copolymer containing 91% of Py was 2 × 105 times higher than the conductivity of the polymer containing 91% of DiPy, indicating that it is possible to tune the conductivity of the film by varying the composition of the initial comonomer mixture.
