N-[(4-Nitrophenyl)thio]- (1a) and N-[(2,4-dichlorophenyl)(thio)]-2,6-diphenyl-4-(3-pyridyl)phenylaminyl (1b), N-[(4-nitrophenyl)thio]- (2a) and N-[(2,4-dichlorophenyl)thio]-4-phenyl-2,6-di(3-pyridyl)phenylaminyl (2b) were generated by PbO₂ oxidation of the corresponding precursors and isolated as radical crystals. For 1b x-ray crystallog. anal. was performed. The magnetic susceptibility measurements were carried out for the isolated radicals using a SQUID magnetometer at 1.8-300 K. The susceptibilities of 1a and 2a were analyzed in terms of a 1-dimensional (1D) antiferromagnetic (AFM) regular Heisenberg model with exchange interaction of 2J/k_B=-63.4 and -17.8 K, resp., and that of 1b was interpreted in terms of a 1-dimensional AFM alternating Heisenberg model with 2J/k_B = -12.8 K and α 0.91. However, that of 2b was explained in terms of a 1-dimensional ferromagnetic regular Heisenberg model with 2J/k_B = 22.4 K.

Saito, Hitoshi published the artcileFacile synthesis of fluorene-based π-conjugated polymers via sequential bromination/direct arylation polycondensation, Safety of Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2015), 53(19), 2198-2201, database is CAplus.

The synthesis of fluorene-based p-conjugated polymers via sequential bromination and direct arylation was demonstrated. Bromination of 9,9-dioctylfluorene using BTMA Br3 efficiently proceeded and barely inhibited the following direct arylation polycondensation, successfully giving π-conjugated polymers. This is the first example of the facile synthesis of π-conjugated polymers in a one-pot fashion, without the need for prior preparation and purification of dibrominated aromatic monomers as well as organometallic monomers, and the bromination reaction using BTMA Br3 is also available to other aromatic compounds such as thiophene and carbazole derivatives Therefore, the fundamental step-economical protocol described here should present new insights for the synthesis of π-conjugated semiconducting materials.

Tripathi, Ayushi published the artcileOptimization of Thermoelectric Properties of Polymers by Incorporating Oligoethylene Glycol Side Chains and Sequential Solution Doping with Preannealing Treatment, SDS of cas: 111865-47-5, the publication is Macromolecules (Washington, DC, United States) (2020), 53(16), 7063-7072, database is CAplus.

Two types of p-type thermoelec. (TE) polymers with alkyl (PCPDTSBT) and oligoethylene glycol (OEG) side chains (PCPDTSBT-A) on an sp²-hybridized olefinic bis(alkylsulfanyl)methylene-substituted cyclopentadithiophene backbone are synthesized. Interestingly, the OEG-substituted polymer, PCPDTSBT-A, exhibits significant self-doping compared to PCPDTSBT, where the polaron d. of the former is 2.3 × 10¹⁶ mm^-3 (vs. 7.9 × 10¹⁴ mm^-3 for PCPDTSBT) without external doping. Changing the side chains also induces a completely different polymer chain orientation in the PCPDTSBT-A (face-on) and PCPDTSBT (edge-on) films. The effect of doping with 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F₄TCNQ) on the morphol. and TE properties of the polymers with different side chains is studied. Sequential solution doping (SQD) is performed by overcoating the preannealed polymer films with F₄TCNQ solution, which affords highly effective doping without disrupting the morphol. of the crystalline films, especially for PCPDTSBT-A with OEG side chains. Resulting from the synergistic effect of the OEG side chains and SQD, PCPDTSBT-A exhibits remarkably improved elec. conductivity (53.8 S cm^-1) with a higher power factor (40.4μW m^-1 K^-2), compared to PCPDTSBT, for which the maximum elec. conductivity is 1.4 S cm^-1 and the power factor is 1.8μW m^-1 K^-2. In addition, the transport coefficient of PCPDTSBT-A, determined by applying the Kang-Snyder model (2.40 × 10^-2 S cm^-1), is superior to that of PCPDTSBT (3.59 × 10^-3 S cm^-1), thereby showing the excellence of the developed strategy for improving the performance of TE polymers.

Ju, Xiuping published the artcileSynthesis and electrochemical capacitive performance of thieno[3,4-b]pyrazine-based Donor-Acceptor type copolymers used as supercapacitor electrode material, Synthetic Route of 52431-30-8, the publication is Electrochimica Acta (2017), 36-48, database is CAplus.

Two novel donor-acceptor-donor type monomers were synthesized by using thieno[3,4-b]pyrazine (TPZ) as the acceptor units (A) and 3-methylthiophene or 3-methoxythiophene as the donor units (D). The as-prepared D-A-D monomers were named as MOTP and MTP, resp. These two monomers could be facilely polymerized on the glass carbon electrode (GCE) via a potentiostatic method, and the resultant D-A-D alternative conjugated polymers were referred as PMOTP and PMTP. The obtained conjugated polymers were routinely characterized by FT-IR, SEM and TGA at first. Then, as supercapacitor electrode materials, they were further investigated in detail by cyclic voltammetry (CV), constant galvanostatic charge-discharge (GCD) and electrochem. impedance spectroscopy (EIS) methods The GCD results showed that the polymer-modified GCEs had high specific capacitances of 678.2 and 319.1 F/g, for PMOTP and PMTP, resp., at a c.d. of 1 A/g. Excellent switching stabilities were also observed for both polymer-modified GCEs, with the high retention rates of 77.3% and 53.4% for PMOTP and PMTP, resp., after 1000 times of charge-discharge cycling at a c.d. of 10 A/g. Notably, the maximum energy densities of 22.4 Wh/kg and 7.94 Wh/kg were attained at the power d. of 0.55 kW/kg for the sym. supercapacitor based on PMOTP and PMTP, resp. The excellent performances of these two D-A-D type conjugated polymers make them to be the promising electrode materials for energy-storage and conversion applications.

Zhang, Yan published the artcileThree novel donor-acceptor type electrochromic polymers containing 2,3-bis(5-methylfuran-2-yl)thieno[3,4-b]pyrazine acceptor and different thiophene donors: Low-band-gap, neutral green-colored, fast-switching materials, Recommanded Product: 2,5-Dibromo-3,4-dinitrothiophene, the publication is Journal of Electroanalytical Chemistry (2018), 7-19, database is CAplus.

Three novel donor-accept type electrochromic polymers with very low band gap, PMFTTP, PMFBTTP and PMFMOTTP, were prepared via electrochem. polymerization, employing 2,3-bis(5-methylfuran-2-yl)thieno[3,4-b]pyrazine as the acceptor units and thiophene, butylthiophen and methoxythiophene as the donor units, resp. All the polymers were comparatively studied by cyclic voltammetry (CV), scanning electron micrographs (SEM), UV-visible-NIR spectroscopy and colorimetry. PMFTTP and PMFBTTP showed obvious color change from green color to brown in the oxidation process, while PMFMOTTP exhibited color change from brick red to dark gray. And the three polymers possessed very low optical band gaps in the following order: PMFTTP (1.23 eV) > PMFBTTP (0.88 eV) > PMFMOTTP (0.74 eV), which demonstrated the different election-donating ability of thiophene or its derivatives The electrochromic kinetic studies manifested that the polymers presented satisfactory optical contrasts (ΔT%) in the near IR region (NIR), which were 35%, 67% and 60% for PMFTTP, PMFBTTP and PMFMOTTP, resp. Also, the polymers also displayed short switching times (<1 s at any wavelengths), high coloration efficiencies (around ∼200 cm²/C) and outstanding robust stabilities, suggesting the probability of being the promising candidates for the electrochromic devices. In summary, the above pos. results, especially the neutral green color and the very low band gap, had important theor. significance for the application and development of electrochromic polymers.
