Summary: This article presents an unprecedented polymer (poly(thiophene iminoborane)) which is a boron-nitrogen analogue of the well-established conjugated organic polymer poly(thiophene vinylene). The polymer is synthesized through a selective Si/B exchange polycondensation reaction using a 2,5-diborylthiophene and a 2,5-diaminothiophene derivative. A facile synthetic strategy is devised for the latter, making it easily accessible. The novel polymer and a series of monodisperse thiophene iminoborane oligomers show systematic bathochromic shifts in their absorption spectra with increasing chain length, indicating extended π-conjugation over the B-N units along the backbone, which is further supported by TD-DFT calculations.

Summary: This study designed and synthesized an organometallic nickel complex containing thieno[3,2-b]thiophene units. Composite films of the nickel complex and polyvinylidene difluoride, prepared via a simple solution process, exhibited remarkably high n-type conductivity and air stability of the thermoelectric power factor. The introduction of thieno[3,2-b]thiophene core into the backbone of the nickel complex significantly influenced the orientation within the composite films, as indicated by grazing-incidence wide-angle X-ray diffraction analysis.

Summary: The aggregation modes of l-phenylalanine- or d-glucose-functionalized phenylene-thiophene oligomers were studied using UV-Vis absorption and electronic circular dichroism spectroscopies. ECD measurements were found to provide superior information about the supramolecular organization and detect multiple aggregation pathways, difficult to identify with UV-Vis absorption alone. The influence of chiral pendant groups and pi-conjugated lengths on chiroptical response was elucidated, highlighting the importance of controlling different aggregation modes for preparing thin films with tunable chiroptical features for opto-electronic applications.

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.

Summary: This study focuses on the effect of trifluoroacetic acid protonation on polyazomethines in the presence and elongation of alkoxy side chains, as well as the influence of environmental dielectric constants on the doping process. The presence of alkoxy side chains is necessary for protonation, with shorter methoxy side chains reacting faster than longer octyloxy side chains, especially in low-polar media. Acid doping results in a distinct bathochromic shift of absorption band, while electrochemical studies indicate better p-type behavior post-protonation in acetonitrile.

Summary: Hydrophobic coatings inspired by the lotus effect have gained popularity for their ability to solve various problems. The sol-gel method, utilizing silica, alumina, and titania, is explored as an environmentally friendly approach to produce water-based hydrophobic coatings. This study focuses on producing water-based hydrophobic coatings for cotton and polyester fabrics using a one-step sol-gel method. The coated fabrics exhibited improved hydrophobic properties, altered surface morphologies, and lower air permeability compared to uncoated fabrics.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
