AI Article Synopsis

  • A new self-assembled film was created using a polyoxomolybdate and a hemicyanine, demonstrating uniformity and reproducibility.
  • The film forms J-aggregates, indicated by UV-visible spectral analysis.
  • Photoelectrochemical tests revealed that the film generates a stable cathodic photocurrent, achieving a density of 5.1 μA/cm² under specific light conditions.

Article Abstract

A new electrostatically self-assembled film has been successfully prepared on quartz and indium-tin-oxide (ITO) coated glass substrates by alternating adsorption of a wheel-shaped polyoxomolybdate {Mo154} and a hemicyanine of (E)-1,1'-methylenebis(4-(4-(dimethylamino)styryl)pyridinium) bromide (H1). The UV-visible spectra demonstrated that the film was uniform, reproducible, and the H1 in the film forms the J-aggregation. Photoelectrochemical investigations showed that the films can generate stable cathodic photocurrent, and the cathodic photocurrent density of three-layer film was 5.1 microA/cm2 while irradiated with 100 mW/cm2 polychromatic light of 730 nm > lambda > 325 nm at an applied potential of -0.3 V versus saturated calomel electrode.

Effective modifications for the buried interface between self-assembled monolayers (SAMs) and perovskites are vital for the development of efficient, stable inverted perovskite solar cells (PSCs) and their tandem photovoltaics. Herein, an ionic-liquid-SAM hybrid strategy is developed to synergistically optimize the uniformity of SAMs and the crystallization of perovskites above. Specifically, an ionic liquid of 1-butyl-3-methyl-1H-imidazol-3-iumbis((trifluoromethyl)sulfonyl)amide (BMIMTFSI) is incorporated into the SAM solution, enabling reduced surface roughness, improved wettability, and a more evenly distributed surface potential of the SAM film.

Self-assembled monolayers (SAMs) have displayed unpredictable potential in efficient perovskite solar cells (PSCs). Yet most of SAMs are largely suitable for pure Pb-based devices, precisely developing promising hole-selective contacts (HSCs) for Sn-based PSCs and exploring the underlying general mechanism are fundamentally desired. Here, based on the prototypical donor-acceptor SAM MPA-BT-BA (BT), oligoether side chains with different length (i.

Graphene and its derivatives, such as graphene oxide (GO) and reduced graphene oxide (rGO), have propelled advancements in biosensor research owing to their unique physicochemical and electronic characteristics. To ensure their safe and effective utilization in biological environments, it is crucial to understand how these graphene-based nanomaterials (GNMs) interact with a biological milieu. The present study depicts GNM-induced structural changes in a self-assembled phospholipid monolayer formed at an air-water interface that can be considered to represent one of the leaflets of a cellular membrane.

In this study, we have investigated the surface-enhanced Raman scattering (SERS) spectra of myoglobin on silver substrates with different morphology. The aim was to determine the optimal parameters of analyte and substrate preparation for obtaining of high-amplitude SERS spectra of proteins. It is shown that not only the morphology of the silver film, but also the method of analyte molecules deposition on the SERS substrate plays an important role.
