The oxidation of a simple p-methoxyphenol derivative by HClO induces an intramolecular charge transfer from the end phenyl units to the middle benzoquinone, which leads to colorimetric and fluorescent changes. This detection can be run in aqueous solution with high selectivity over other reactive oxygen species.

the polymer N‐PFP50 and the model compound FMOPF, the absorption and fluorescence spectra could be assigned to the fluorene‐alt‐methoxyphenol. All the conjugated polymers (CPs), regardless of the content of methoxyphenolmoieties, exhibit good sensitivity to hypochlorite/hypochlorousacid (HClO) because of the superquenching effect of CPs. On the contrary, the absorption changes of the polymers N‐PFPx

A degradable polymeric nanotube (NT) dispersant comprises a multiplicity of NT associative groups that are connected to a polymer backbone by a linking group where there are cleavable groups within the polymer backbone and/or the linking groups such that on a directed change of conditions, bond breaking of the cleavable groups results in residues from the degradable polymeric NT dispersant in a manner where the associative groups are uncoupled from other associative groups, rendering the associative groups monomelic in nature. The degradable polymeric nanotube (NT) dispersant can be combined with carbon NTs to form a NT dispersion that can be deposited to form a NT film, or other structure, by air brushing, electrostatic spraying, ultrasonic spraying, ink-jet printing, roll-to-roll coating, or dip coating. The deposition can render a NT film that is of a uniform thickness or is patterned with various thicknesses. Upon deposition of the film, the degradable polymeric nanotube (NT) dispersant can be cleaved and the cleavage residues removed from the film to yield a film where contact between NTs is unencumbered by dispersants, resulting in highly conductive NT films.
Fluorescent probes are powerful tools for the investigations of reactive oxygen species (ROS) in livingorganisms by visualization and imaging. As one of the most important of the natural reactive oxygen species (ROS), hypochlorous acid (HClO) plays a crucial role in various physiological and pathological processes. We report herein a new redox-switchable NMOF of UiO-68-ol via a direct ligand modification
