Singlet molecular oxygen

Ebook "Heterogeneous photocatalysis using inorganic semiconductor solids" underscores the essential principles of photocatalysis and provides an update on its scientific foundations, research advances, and current opinions, and interpretations. It consists of an introduction to the concepts that form the backbone of photocatalysis, from the principles of solid-state chemistry and physics to the role of reactive oxidizing species.

Treatment of hydrogen peroxide with a polymer-supported hypervalent iodine compound, poly[4-diacetoxyiodo] styrene (PDAIS), generates singlet molecular oxygen ( 1 O2). Singlet oxygen generation was proved by trapping with typical organic compounds such as conjugated dienes, aromatic dienes, and electron-rich alkene. When compared to monomer analogue, the use of PDAIS in peroxidation of substrates gave slightly better yields (45%–96%). Regeneration and reuse of PDAIS showed similar activity. The mechanism underlying generation of singlet oxygen and reaction scope was examined.

A new luminescent probe based on β- diketonate Eu3+ complex, Eu (TFPB)3AnPy, where AnPy is (1-(anthracen-9-yl)-N-(pyridine-2-ylmethyl) methaneamine and TFPB is benzoyltriluoro acetone was successfully synthesized. The molecular structure of Eu (TFPB)3AnPy determined by SC-XRD show an eight coordination in which Eu3+ is bonded to six oxygen atoms of three TFPB and two nitrogen atoms of the AnPy ligand. The complex could act as a highly sensitive luminescent probe for 1O2 that can be applied in biological systems.
