Summary: In this study, two donor-acceptor-type polymers (P-BDF and P-NDF) based on benzodifuranone (BDF) and naphthodifunarone (NDF) were designed and synthesized with different backbone structures. It was found that the planar backbone conformation of P-BDF led to superior charge transport performance compared to P-NDF. The results suggest that the main chain coplanarity of polymer semiconductors is more essential than the sole extension of pi-conjugations.

Summary: In this study, the quasi-1D electrical current through long single conjugated polymer chains was measured using coupled ionic-electronic charge transport. It was found that fluctuations between internal conformations of the individual polymers resulted in abrupt, multilevel switches in the electrical current, consistent with theoretical simulations. Additionally, the results provided insights into the dynamics of random-coil polymers and the potential use of semiconducting polymers as electrical labels for single-molecule sensing assays.

Summary: The effect of fluorination of a conjugated polymer backbone on charge trapping and the operational stability of organic field-effect transistors is investigated. It is found that although fluorination can increase charge carrier mobility, it leads to poor operational stability due to the presence of a greater degree of shallow trapping and the presence of minority charge carriers.

Summary: Reported is the use of polynaphthalenediimide (PNDI)-based copolymers containing novel fluorinated selenophene-vinylene-selenophene (FSVS) units as efficient materials for n-type organic electrochemical transistors (OECTs) and organic field-effect transistors (OFETs). The PNDI polymers with oligo(ethylene glycol) (EG7) side chains P(NDIEG7-FSVS) achieved a high carrier mobility of > 0.2 F cm-1 V-1s-1, outperforming benchmark materials by two orders of magnitude. The conjugated polymer with octyldodecyl (OD) side chains P(NDIOD-FSVS) exhibited low energetic disorder and ultra-low activation energy, resulting in high electron mobility in n-type OFETs.

Summary: Poly(3,4-ethylenedioxythiophene) (PEDOT) and its derivatives have potential in bioelectrode development, but improvements are needed in biocompatibility and prevention of nonspecific adhesion. In this study, six ethylene glycol (EG)-functionalized EDOTs with different EG lengths and end groups were synthesized and investigated. The PEDOT-coated electrodes showed different surface and electrochemical properties based on the EG length and end group. Surface with -OCH3 groups exhibited higher electrochemical activity and lower impedance, and longer EG lengths and -OCH3 groups reduced platelet adhesion.

Summary: This study develops an efficient solar steam generation platform based on a hydrophilic metal-organic framework for producing drinkable water from seawater or wastewater. By coating Ti2O3 nanoparticles blended with poly(hydroxymethyl EDOT) (Ti2O3@PEDOT-OH) as photothermal conversion nanocomposites on synthesized CAU-10-H membranes, a transmembrane temperature gradient is created, optimizing water adsorption and desorption efficiency. The device with 13 μm thickness of CAU-10-H achieves the highest average evaporation rate of 2.20 kg.m- 2.h- 1 and an evaporation efficiency of 98%. Additionally, the ion concentrations of the produced water are lower than the drinkable water standard.

Summary: Efficient removal of gas bubbles is crucial for enhancing the reaction efficiency and electrode stability in the hydrogen evolution reaction (HER). In this study, superaerophobic electrode surfaces were created by combining hydrophilic functionalized poly(3,4-ethylenedioxythiophene)(PEDOT) with colloidal lithography. The electrodes were fabricated using polystyrene beads as templates and electropolymerization of EDOTs with different functional groups. The results showed that the modified electrode with poly(EDOT-SuNa) and 200 nm PS beads exhibited the best hydrophilicity and significantly reduced the overpotential required for the HER.

Summary: In this study, copolymer films of corannulene-carbazole (CCZ) and 3,4-ethylenedioxythiophene (EDOT) were developed as near-infrared (NIR) electrochromic windows. Two strategies, twisted structure and copolymerization, were used to enhance the NIR electrochromic performance. CCZ, with its twisted polymer network, exhibited better NIR electrochromic performance compared to planar carbazole-based materials. Electrochemical impedance analysis showed that the twisted structure improved NIR electrochromism by increasing ion transportation. Additionally, EDOT was employed to improve optical contrast in the NIR region. The copolymer films showed the highest optical contrast (45% at 1000 nm) when a suitable ratio of EDOT to CCZ was used, indicating that copolymerization with EDOT could further enhance NIR electrochromism. This study provides critical insight into molecular design of corannulene-based materials for electrochromic applications.

Summary: This study developed an electrochemical biosensor for the detection of leukocyte esterase (LE) and nitrite, which are markers for urinary tract infections (UTIs). The biosensor demonstrated good performance with a linear range of 9.1-131 μM for LE and 0.2-590 pg/L for nitrite, and detection limits of 6.2 μM and 0.2 pg/L, respectively. In clinical testing, the biosensor showed 100% sensitivity and 87.5% specificity for diagnosing UTIs. This biosensor offers a potential alternative to urine strip tests due to its simplicity, rapidity, multi-analyte detection, and high sensitivity.

The introduction of nonconjugated linker alkyl chain helps the polymer display excellent electrochromic behavior in both neutral and doped states, and pursue a transparent-to-color effect. However, the length of the alkyl chain affects the optical contrast and specific capacitance of the polymers.
