Summary: Solution-processable redox-active materials with ion conductivity are necessary for electrochemical applications, and the thin films should be insolubilized for use with electrolyte solutions. In this study, a perylene bisimide derivative with an azacrown ether moiety was synthesized, which formed a rectangular ordered columnar liquid crystalline phase. The compound formed complexes with lithium triflate and sodium triflate in a 1:1 molar ratio, but phase separation occurred when mixed with potassium triflate. The compound could be dissolved in non-polar organic solvents and thin films were produced using the spin-coating method. AFM studies showed fibrous nanostructures on the film surfaces, indicating the formation of supramolecular columnar structures. By exposing the spin-coated thin film to trifluoromethanesulfonic acid vapors, the film was insolubilized via an in situ ring-opening polymerization process. The resulting insolubilized thin film exhibited electrochromism between red neutral and violet dianion states.

Summary: The study shows that a bulk photovoltaic effect can be achieved in a chiral smectic crystal phase doped with specific additives. The polarity of the photovoltaic effect can be adjusted by changing the polarization bias. Aggregation of fullerene derivatives into microcrystals promotes hole-electron dissociation, leading to high efficiency of photocurrent generation.

Summary: This study investigates the influence of the polarity of polymer matrices on persistent room-temperature phosphorescence (pRTP). It is discovered that intense phosphorescence emission can be achieved in highly polar matrices such as polyacrylic acid (PAA). The dipole-dipole interaction between the polar fluorophore and polar matrix is proposed to stabilize the excited state and facilitate the generation of efficient room-temperature phosphorescence emissions.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

Summary: In this study, a new spin-gapless semiconductor material CoFeMnSn is reported, and its stable structure and spin-polarized band structure are determined through experimental realization and theoretical calculations. The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
