Summary: Recent research on organic semiconductors has shown that the composition and subtle changes in structure of organic materials significantly impact their bulk properties, particularly in terms of charge transport. Synthesizing new conjugated materials that can self-organize and introducing hydrogen bonding to form hydrogen-bonded material superstructures are effective strategies in obtaining well-ordered material films.

Summary: Understanding the intermolecular forces in ionic liquids is crucial for understanding their properties. This study investigated weaker hydrogen bonding in aprotic liquids by combining computational study and far-infrared spectroscopy on four imidazolium-based ILs with different anions. The results demonstrated that the ion pairs in these ILs exhibit moderate to weak hydrogen bonding with the anions, with specific absorption bands corresponding to hydrogen bond stretching observed in the far-infrared spectrum. Additionally, phase transitions as a function of temperature were detected, and the difference in energy between H-bonded and dispersion-governed configurations was evaluated from the infrared spectra analysis.

Summary: Au center dot center dot center dot H X (X = N or C) hydrogen bonding is gaining interest in both intrinsic study and operability in different fields. The role of these interactions in the stabilization of gold(I) complexes has been studied, but their role in the minimum free energy reaction pathway of a given catalytic process remains unexplored. Here, we report that complex [Au(C.CPh)(pip)] (pip = piperidine) catalyzes the A3-coupling reaction for the synthesis of propargylamines, thanks to the directing role of Au(I) in weak hydrogen bonding interactions with the reactants along the free energy profile. Density Functional Theory (DFT) calculations, along with topological non-covalent interactions (NCI), interaction region indicator (IRI), and quantum theory of atoms in molecules (QTAIM) analysis, accurately describe these interactions.

Summary: The study synthesized three polymers by copolymerizing DPP with monothiophene units having different substituents, and found that they exhibited similar photophysical and electrochemical properties. All three polymer specimens had a maximum hole mobility value of 0.37 cm(2) V-1 s(-1), with the chlorine-substituted DPP polymer showing promising amorphous semiconductor properties that make it a good candidate for commercial OFETs. The findings suggest that the newly developed polymeric semiconductors are viable for incorporation in organic field-effect transistors.

Summary: Electrocatalysis plays a crucial role in achieving sustainable chemical production using abundant resources and renewable energy. In this study, we developed an effective electrochemical method for producing hydrogen peroxide (H2O2) using only pure water and oxygen. Nickel (II) oxide (NiO) was used as the electrocatalyst for oxygen evolution reaction (OER) at the anode, while a conducting polymer poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) drove the oxygen reduction reaction (ORR) at the cathode to generate H2O2. The conversion efficiency of the H2O2 electrochemical refinery was limited by unbalanced ionic transport in the solid electrolyte, but optimization of operation conditions achieved an efficiency of 80%.

Summary: A heavy metal-free synthetic methodology for the one-step conversion of ketones into 4,5,6,7-tetrafluorobenzofurans (F(4)BFs) has been developed. It has favorable qualities such as the use of readily available substrates, broad scope, scalability, and good reaction yields. The synthesized benzofurans were previously inaccessible, and this methodology also enables the preparation of furo[2,3-b]pyrazines and difuro[2,3-c:3',2'-e]pyridazine, which have not been explored before.

Summary: Chiral fluorescent macrocycles, consisting of dimethyl 2,5-diaminoterephthalate units, can be easily synthesized from inexpensive building blocks. Depending on the concentration, the reaction mainly produces a paracyclophane-like dimer or a triangular trimer. These macrocycles exhibit fluorescence in solution and the solid state, with red-shifted maxima as the size of the macrocyclic ring decreases. Chirality affects their absorption and emission of circularly polarized light.

Summary: Replacing toxic lead atoms in halide perovskite materials with non-toxic elements has been explored to develop environmentally friendly perovskite solar cells. In this study, the effect of doping hybrid perovskite MAPbI(2.6)Cl(0.4) with non-toxic elements, such as Mg2+ and Zn2+, was investigated. The structural, morphological, and optical properties of the doped samples were analyzed, and the doped films were utilized as photoactive layers in solar devices to evaluate their photovoltaic performance. Zn doping showed better results in terms of film quality and the MAPb1(-x)Zn(x)I(2.6)Cl(0.4) based solar cells exhibited improved photovoltaic performances compared to pristine MAPbI(2.6)Cl(0.4) based devices.

Summary: Visible-light-driven semiconductor photoelectrodes utilizing organic polymeric photocathodes have been fabricated in this study. Different derivatives of poly(4,7-di(thiophen-2-yl)benzo[c][1,2,5]thiadiazole) (pThBTD) were employed and the monomer dithienobenzodithiazole was directly polymerized on an electrode via electropolymerization or iodine-vapor-assisted polymerization. The electropolymerization method resulted in better performing photocathodes with wide visible light absorption and suitable stability. The critical factors affecting oxygen reduction photocurrents, such as thickness, wettability, and pH, were evaluated. The organic photoelectrocatalyst showed high photocathodic oxygen reduction currents and photovoltages, with stable production of H2O2 over at least 8 h with high faradaic yield.

Summary: The technology of perovskite solar cells (PSC) is approaching the consumer market, but reducing the toxicity during their fabrication remains a challenge. This study explores the replacement of the toxic solvent dimethylformamide (DMF) with presumably less toxic alternatives, such as N-methyl-2-Pyrrolidone (NMP) and ethyl acetate (EA), for the preparation of K(0.1)FA(0.7)MA(0.2)PbI(2.8)Cl(0.2) (KFAMA) hybrid perovskite. The results show promising potential for reducing toxicity with the partial substitution of DMF with NMP and EA solvents, while maintaining the same deposition parameters.

Summary: Polyacrylic acid complexed with polyaniline (PAA/PANI) composite materials have the potential to form organic mixed ion-electron conductive (OMIEC) films, which can be used in optoelectronic and energy storage applications. The composite films are formed through an acid-base reaction, resulting in strong electrostatic interactions and intermolecular hydrogen bonds between PANI and PAA. The separation of PANI-rich domains from PAA-rich matrix in the composite films is observed. The electrical conductivity of the composite films is higher when the content of PANI is 33 wt%, due to the high ionic-electronic coupling at the interface between phase-separated regions.
