Summary: This study proposed a chemical polymerization method to produce conducting polymer PEDOT on the electrode sites. Compared with electropolymerization, it does not require each electrode site to be connected to a power source. The method is competitive in batch preparation and is particularly suitable for neural microelectrodes prepared by a microelectromechanical systems (MEMS) process.

Summary: This study aimed to obtain a neutral state black electrochromic polymer by adjusting the optical absorbance across the entire visible region. Two monomers, TTBTT and EDOT, were combined in the same polymer backbone through electrochemical copolymerization. Varying the monomer feed ratios resulted in different optical contrast, switching response, and color hues for each copolymer. The copolymer with more EDOT units showed higher optical contrast and faster switching response. A dual-type electrochromic device was also successfully constructed using the copolymer.

Summary: In this study, two novel bipyridine-based Ru(II) complexes with different number of EDOT groups were synthesized and electrochemically polymerized to form metallopolymers. The resulting polymers exhibited ambipolar and multichromic behavior, with reversible redox activity in the cathodic region and redox activity of the conjugated backbone in the anodic region. Increasing the number of polymerizable units improved film quality and increased color diversity. Copolymerization improved band gap and switching time, further widening the color range of the polymers.

Summary: Electrochromism of organic compounds is well-known and most research is focused on anodic coloring materials. Developing efficient cathodic electrochromic materials is challenging due to the stability issues of electron accepting materials. However, stable cathodic coloring organic materials are highly desired. Four phthalimide derivatives with different chemical structures were synthesized and analyzed. The optimized phthalimide structure allows for the development of stable cathodic electrochromic materials.

Summary: Poly(3,4-ethylenedioxythiophene) (PEDOT) is an excellent electrochromic material with inherent infrared (IR) electrochromic properties, making it promising for intelligent IR thermal management. This study investigates the mechanism underlying the IR electrochromic performance of PEDOT by employing eight common dopants and in situ electrochemical deposition. The results show that the delocalization of polarons and bipolarons on PEDOT chains is related to the positively polarized sulfur atoms in the thiophene rings, which determines the reflectance regulation of PEDOT films. The diverse IR control capabilities of different doped PEDOT devices mainly result from the variation in charge carrier concentration in the oxidized state.

Summary: This study investigates the ORR behavior of a series of electropolymerized PEDOT films and finds that the doping level of the polymer is influenced by the counterion type and the presence of a conductivity enhancer, which controls the ORR pathway in PEDOT films. High levels of intrinsic doping result in films with H2O2 as the major ORR product.

Summary: Several electro-active monomers based on triphenylamine end capped and substituted central naphthalenetetracarboxylic diimide were designed and developed to study the effect of substituent on electropolymers formation and the chromic effect of prepared films on conductive surface. The density functional theory studies showed that HOMO was located on triphenylamine unit, responsible for electro-polymerization process, LUMO resided on the central naphthalene core, and all substituents were not coplanar with naphthalene moiety. The films exhibited reversible multiple colour changes with relatively good response times, optical contrast, switching stabilities, and coloration efficiencies.

Summary: Recently, it has been found that poly(3,4-ethylenedioxythiophene) (PEDOT) fibers can be produced from bipolar electrodes in acetonitrile solution using alternating current (AC)-bipolar electro-polymerization. This study extends this method to ionic liquid (IL) media and explores the growth of PEDOT fibers in three different ILs. The obtained PEDOT morphologies were found to be influenced by the physicochemical properties of the ILs.

Summary: Conducting polymers are promising transparent supercapacitor electrode materials due to their high conductivity, environmental stability, light weight, and ease of synthesis. We developed a synthetic method to covalently link poly(3,4-ethylyenedioxythiophene) (PEDOT) and glass, which overcomes the poor adhesion and low cycling stability challenges. This method enables the fabrication of current collector-free planar supercapacitor electrodes on any glass surface.

Summary: In this study, copolymers with various molar ratios of 3,4-ethylenedioxythiophene (EDOT) to thiophene (Th) were synthesized as conductive additives in hydrogels. By doping engineering and incorporating P(EDOT-co-Th) copolymers, hydrogels exhibited excellent physical/chemical/electrical properties. The mechanical strength, adhesion ability, and conductivity of hydrogels were found to be highly dependent on the molar ratio of EDOT to Th. Higher EDOT content resulted in stronger tensile strength and higher conductivity, but lower elongation break. After comprehensive evaluation of the properties and cost, the hydrogel incorporated with a 7:3 molar ratio P(EDOT-co-Th) copolymer was found to be the optimal formulation for soft electronic devices.
