“…The reflectance spectrum of Pbis‐Th2PC 60 (Figure 3c) shows two bands respectively at 230 and 310 nm of C 60 and also a new band at 430 nm to be compared with the absorbance spectrum of the monomer in Figure 1c. This new band is attributed to the thiophenic conjugation in the polymer chain [29a] . Also, the UV‐vis spectrum in Figure S4 shows the semitransparency of the polymeric film with a transmittance of about 78 % at 430 nm, corresponding to an absorbance value equal to 0.11.…”

“…As shown in Figure 2, the bis‐Th2PC 60 monomer displays an amphoteric redox behavior with an oxidation onset potential (E onset ) at 1.1 V and one oxidation peak potential at 1.3 V. These can be attributed to the oxidation of the bithiophene moieties, [33] and three reduction processes at −0.72 V, −1.13 V and −1.80 V versus Ag/Ag + which can be ascribed to the fullerene core. The cathodic peaks potentials are typical of the polythiophene fulleropyrrolidine systems, [29a] and they are shifted towards more negative potentials compared to those derived from the cyclic voltammogram of pure C 60 (see Figure S1a in the Supporting Information). Also, the first and second reduction waves are reversible, while they become irreversible after scanning past the fourth reduction peak at −2.20 V (Figure S1b).…”

A novel bithiophene-fulleropyrrolidine bisadducts system (bis-Th2PC 60) was synthesized and electropolymerized by chronoamperometry onto flexible ITO/PET substrates. The resulting semitransparent thin film was characterized by XPS, FT-IR, cyclic voltammetry and optical techniques, confirming the good outcome of the electropolymerization process. AFM investigations permitted to highlight an inherent disordered granular morphology, in which the grain-to-grain separation depends upon the application of bending. The electrical resistance of the thin film was characterized as a function of bending (in the range 0°-90°), showing promising responsivity to low bending angles (10°-30°). The ΔR/R 0 variations turn out to be 8 %,16 % and 20 % for bending angles equal to 10°, 20°and 30°, respectively. This study represents a first step towards the understanding of piezoresistive properties in electropolymerized fullerenes-based thin films, opening up applications as bending sensor.

“…In the literature, many studies are devoted to examining the formation of polymeric materials based on polythiophenes or polythiophene derivatives and fullerenes or fullerene derivatives. [43][44][45][46][139][140][141][142][143][144][145][146][147][148][149][150][151][152] Because the oligo-and polythiophenes possess advantageous electronic properties, these materials show promise for use in applications mainly in organic electronics [45,138,139,147,148] and photoelectronics. [43,44,46,137,[141][142][143][144][145][146][147] In these "double cable" systems, the polythiophene backbone and fullerene pedant moiety independently retain their ground state properties.…”

structure, which can be easily covalently modified. Progress in extensive organic chemistry of fullerene development facilitates the production of a variety of fullerene derivatives with different structures and physicochemical properties. Additionally, the polyhedral structure of fullerenes containing a large number of bonding sites provides an opportunity for a wide range of covalent modifications. Polymeric structures containing fullerene moieties represent a particularly large class of materials in terms of their number, composition, structure, morphology, and physicochemical properties. [24-29] Some of the most common structures of these polymeric materials are schematically shown in Figure 1. The simplest and most common structures are composites formed from the polymeric chains and fullerenes. Fullerenes form a crystalline phase in the polymeric matrix [30] or are incorporated as guest molecules into polymeric chain containing host moieties. [31] In both cases, covalent interactions are not formed between fullerenes and the polymeric network. However, van der Waals and electrostatic interactions, as well as possible charge transfer between both components of the composite significantly modulate the electronic structure of the polymer/fullerene interphase. [32,33] A stronger electronic interaction between the polymer component and fullerene moieties is expected for the system in which carbon cages are covalently bound to the polymeric chain or covalently incorporated into the polymeric backbone. In the case of in-chain structures, fullerene moieties are separated by short organic conjugated linkers, [34-37] small inorganic linkers, [37-39] or metal atoms and metal complexes. [7,8,29,40-42] A large group of fullerene-based materials consists of organic conducting polymers containing fullerenes attached covalently to the polymer chain by the linker. [43-46] The physicochemical properties of these materials depend on the polymer chain, linker structures, and the density of fullerene moieties within the polymeric material. Similar to olefins, fullerene form homopolymers through [2+2] cycloaddition. [47-51] Fullerene homopolymers, in-chain and side chain fullerene polymers can be cross-linked to form 3D polymeric structures. A large number of reactive π-bond centers in the fullerene moiety enable the formation of star-shaped macromolecular systems with polymeric chains covalently grafted to the C 60. [52-57] In common structures, the number of linked This article provides a comprehensive review of research related to the formation and electrochemical properties of fullerene-based conducting polymeric materials. The paper begins with an overview of composites containing fullerenes incorporated into the network of a conducting polymer through van der Walls, electrostatic, or guest-host interactions. The properties of these composites are generally a superposition of the properties of the individual components. More attention is devoted to the structures in which fullerene is covalently incorporated into the polyme...
