Allgemeine Beschreibung

Octylphosphonic acid (OPA) forms a self-assembled monolayer (SAM), which serves as a protective anti-corrosive phosphonate layer on a variety of surfaces.

Anwendung

OPA can be used as a surfactant that may be added to silver (Ag)/titanium oxide (TiO2) for uniform dispersion into the polymeric matrix. It may be coated on indium-tin oxide (ITO) substrates, which can be used for super-resolution microscopy. OPA based charge blocking layer may be used to prevent leakage of current in a hybrid dielectric film.

Rapid and quantitative click functionalization of surfaces remains an interesting challenge in surface chemistry. In this regard, inverse electron demand Diels-Alder (IEDDA) reactions represent a promising metal-free candidate. Herein, we reveal quantitative surface functionalization within 15 min. Furthermore, we report the

We report the self-assembly of an extensive inter-ligand hydrogen-bonding network of octylphosphonates on the surface of cesium lead bromide nanocrystals (CsPbBr3 NCs). The post-synthetic addition of octylphosphonic acid to oleic acid/oleylamine-capped CsPbBr3 NCs promoted the attachment of octylphosphonate to the

Flexible Organic Transistors for Biomedical Applications

There is widespread demand for thin, lightweight, and flexible electronic devices such as displays, sensors, actuators, and radio-frequency identification tags (RFIDs). Flexibility is necessary for scalability, portability, and mechanical robustness.

Micro and Nanometer Scale Photopatterning of Self-Assembled Monolayers

Self-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold.
