Summary: The operational stability of organic photovoltaics (OPVs) remains a major challenge for commercialization. By replacing the conventional hole-transporting layer with self-assembled monolayers of specific phosphonic acids, the lifetime and efficiency of OPV devices can be significantly improved. The improved performance is attributed to the stabilized vertical distribution of donor and acceptor components, reducing energetic disorder and non-radiative recombination losses. The application of these phosphonic acids in ternary devices demonstrates even higher efficiency and longer lifetime.

Summary: Investigated the role of self-assembled monolayers in the growth of organic semiconductor thin films. Found that disordered self-assembled monolayer molecules assisted in the surface diffusion of organic semiconductor molecules, resulting in a larger grain size of the thin films. Also discovered that a thick self-assembled monolayer with disordered molecules on the top was beneficial for the high mobility and bias stability of organic thin-film transistors.

Summary: Investigating the conversion of weak interactions on protein surfaces can lead to new insights in drug development. This study used scanning electrochemical microscopy to investigate the conversion from coordination bonds to electrostatic interactions on a simplified protein surface. The results revealed that the conversion was driven by the higher binding affinity between certain amino acids. This work helps in understanding the molecular mechanisms of conversion phenomena on biological surfaces.

Summary: The alkyl linker-based self-assembled monolayer (SAM) has limitations in its hole-transporting capability and stability. In this study, a series of conjugated SAMs with enhanced photo and electrical stability were reported. The conjugated molecular structure not only improves charge transport but also stabilizes the electron-rich arylamines. An optimal conjugated SAM, in combination with a standard triple cation perovskite, achieved efficient inverted PSCs with high stability. The findings suggest that conjugated SAMs are promising for further advancement of inverted PSCs.

Summary: This study investigated the competition between ion-pair and electrostatic interactions on the surface of 3-MPA SAM, finding that the addition of perchlorate anion led to noticeable competition between these interactions. Perchlorate ion exhibited more effective competition with the electrostatic interaction due to its pairing capacities and hydration energy with Fc(+)CH(2)OH.

Summary: This article presents a prototype of a ferroelectric tunnel junction (FTJ) based on a self-assembled monolayer (SAM) of small, functional molecules. The SAM is highly uniform and thin, and exhibits reversible conductance switching. Compared to inorganic material-based FTJs, this approach using SAMs of small organic molecules allows for a higher level of functional complexity while maintaining a robust and simple fabrication process. The technology is expected to find applications in information storage and processing.

Summary: In this study, the plasmonic response of self-assembled monolayer silver nanoparticles was comprehensively investigated using various computational and experimental techniques. The Fano resonance and SERS application were studied, and it was found that the higher-energy antibonding mode is not only from the antibonding dipole-dipole mode, but also from the antibonding quadrupole-quadrupole mode and hybridized magnetic mode. The effects of dimer gap and size were discussed in detail, and a two coupled oscillators model was used to illustrate the mechanism of the Fano resonance.

Summary: The fluorescence pH probe C. SNARF-4F was used to measure the fluorescence spectrum of aqueous electrolytes between mica or silica surfaces at different surface separations. The pH of the aqueous CsCl between mica decreased exponentially with decreasing surface separation. The interfacial pH was found to be influenced by electrolyte concentration, electrolyte species, and substrates, with variations in pH observed at different concentrations and with different cationic species of the electrolytes.

Summary: We have conducted X-ray diffraction measurements and resonance shear measurements to study the structural and viscous changes of OMCTS and n-hexadecane under nanoconfinement. The results indicate that the structural order of OMCTS and n-hexadecane significantly increases under nanoconfinement, especially below 100 nm. The increase in viscosity requires a certain level of ordering.
