“…A flexible free-standing copolymer P17 film, synthesized by electrochemical copolymerization of thieno[3,2-b]thiophene with EDOT, was reported very recently. [90] P17 showed good flexibility, conductivity, and mechanical stability under long-term deformation, color conversion with optical contrast of 50.2% during the charging/discharging process, and attained a high C s of 193 F g −1 at 4 A g −1 in a half cell as compared to polythieno[3,2-b]thiophene (73 F g −1 ) and PEDOT (152 F g −1 ).

Conjugated polymers have attracted growing attention for versatile applications in energy storage due to their potential benefits including low‐cost processing, molecular tunability, environmental benignity, and high mechanical flexibility. In particular, polymer‐based organic electrode materials have shown significant progress in supercapacitor (SC) applications with superior electrochemical behaviors. The performances of SCs are closely related to the intrinsic characteristics of different polymers in the nanoscale and the morphological features of the polymer‐based electrode materials obtained by different fabrication techniques in the macroscale. This review summarizes the design and synthesis of both p‐type and n‐type conjugated polymers, highlighting the pros and cons of three synthesis techniques: electrochemical polymerization, chemical polymerization, and in situ polymerization. The performances of conjugated polymers in SCs, their cycling stabilities, and structure‐performance relationships are discussed. Moreover, the existing challenges and future directions of polymer‐based SCs are considered with respect to energy density, stability, and large‐scale production to promote commercialization.

“…Conducting polymers have emerged as promising high-performance materials due to their tuneable sensitivity adjusted by formation techniques [213,214]. The conducting polymers such as thiophene [215][216][217], aniline [218,219], and pyrrole [217,220] can be obtained by ED, especially by potentiodynamic mode due to the possibility of understanding the mechanism of electrochemical polymerization [221]. The supramolecular arrangement and the properties of conducting polymers can be tuned by changes in the electrolyte solution, monomers, pH, doping, and electrochemical parameters such as potential range and ED time [217,221,222].…”

In recent decades, many research efforts have been dedicated to finding highly sensitive devices for fast and reliable identification and quantification of an expanding range of analytes. As a result, there has been an increased number of publications dedicated to this area and a consequent increase in the number of review papers on the subject. However, unlike most review articles, we chose to explore the impact of supramolecular arrangement (or deeper, when possible, approaching the molecular organization) and assembly variables on sensing performance. This review briefly discusses the methods used to determine the molecular organization of thin films. We also examine various deposition techniques, including Langmuir-Blodgett, Langmuir-Schaefer, Layer-by-Layer assembly, electrodeposition, and spray pyrolysis, describing mainly (but not limited to) the advances in the last five years in developing thin films for sensors, with a particular emphasis on how the supramolecular arrangement can influence the sensing properties of these films.

“…38 In addition, some studies applied the electrodeposition method to prepare the conjugated polymeric lm electrodes because of the high mobility of the polymer chain conformation and naturally composed mesoporous on the electrode during polymerization. [39][40][41][42][43][44][45] Zhang et al designed a donor-acceptor-donor monomer (CDB-EDOT) to prepare ECS electrodes by electropolymerization. The obtained polymer exhibited 4.65 mF cm −2 of areal-specic capacitance at 0.05 mA cm −2 with high coloration efficiency (CE, 158 cm 2 C −1 ), and the corresponding device could run a single yellow LED for more than 60 s. 45 Chao et al reported a conjugated polymer with a dual-redox center (thiophene and TPA) and an electronwithdrawing cyano group by applying the electrodeposition method.…”
