Singlet oxygen, systematically named dioxygen (singlet) and dioxidene, is a gaseous inorganic chemical with the formula O=O (also written as 1. [O. 2] or 1. O. 2), which is in a quantum state where all electrons are spin paired. It is kinetically unstable at ambient temperature, but the rate of decay is slow.
5 sty 2024 · Singlet oxygen (1 O 2) is molecular oxygen in the excited state with high energy and electrophilic properties. It is widely found in nature, and its important role is gradually extending from chemical syntheses and medical techniques to environmental remediation.
Singlet oxygen species are chemically reactive chemical varieties containing oxygen. Also known as light therapy, photodynamic therapy is a treatment for cancers that are near the surface of a body’s tissue, where the light can act on the chemical substances.
6 cze 2018 · Singlet oxygen can react with simple organic molecules, with complex biological molecules and with cellular components with high rate constants. These reactions can be described as archetypical green chemistry processes because they need only the substrate molecule, visible light, air and a catalytic dye component.
In this review the three major reactions of singlet oxygen (1O2) with unsaturated organic molecules, namely the [4 + 2] and [2 +2] cycloadditions as well as the ene oxyfunctionalization are highlight...
Singlet oxygen, O2 (a1Δg), the lowest excited electronic state of molecular oxygen, has been known to the scientific community for ∼80 years. It has a characteristic chemistry that sets it apart from the triplet ground state of molecular oxygen, O2 (X3Σ−g), and is important in fields that range from atmospheri.
6 sie 2024 · One goal of this Review is to summarize recent developments that have broad ramifications, focusing on systems in which oxygen forms a contact complex with an organic molecule M (e.g., a liquid solvent).
