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 …

2024年1月5日 · Singlet oxygen (1O2) 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.

2018年6月6日 · 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.

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.

2023年9月13日 · 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.

2016年1月27日 · Singlet oxygen (1 O 2) is the first electronic excited state of molecular oxygen (O 2). Considered as a distinct chemical entity, its electronic configuration is responsible for its unusual thermodynamic stability but remarkably enhanced reactivity towards other molecules in the singlet state.
