A new bright chemiluminescent reaction: interaction of acetone with solid potassium peroxymonosulfate in the complex of europium nitrate

Chemoluminescence H 4000 A New Bright Chemiluminescent Reaction: Interaction of Acetone with Solid Potassium Peroxymonosulfate in the Complex of Europium Nitrate. -Rapid addition of liquid acetone to a solid mixture of KHSO5 and Eu(NO3)3, preheated for 5 min at 90-200°C leads to bright chemiluminescence, which may be observed even by the naked eye in a slightly darkened room. Dioxirane and/or singlet-oxygen are proposed as key intermediates of the reaction. -(KAZAKOV*, D.; SAFAROV, F. E.; KAZAKOV, V. P.; SCHMIDT, R.; Mendeleev Commun. 18 (2008) 5, 249-250; Inst.

Subject of study. This study investigates the luminescence spectral and kinetic features of singlet oxygen generation in chitosan microfilms (10 µm thick) embedded with an extract of viburnum fruit (Viburnum opulus L.). These films were deposited on both glass and gold film (80 µm thick), with the gold film electrochemically deposited on a rough, modified titanium surface. Aim of study. The aim was to determine the primary photophysical patterns of singlet oxygen dynamics in chitosan films containing viburnum fruit extract, following pulsed monochromatic photoexcitation by a structured titanium surface coated with electrochemically deposited gold. Method. The films were investigated in the visible and near-infrared regions using fluorescence techniques. The luminescence lifetime of Viburnum opulus L. flavonoids in the nanosecond range was measured using multichannel photon counting with a picosecond diode. The lifetime of the flavonoid triplet states and singlet oxygen phosphorescence in the studied extract in the microsecond range under excitation by a pulsed xenon lamp were also recorded. Main results. Long-lived delayed annihilation fluorescence of Viburnum opulus L. flavonoid molecules in the 590 nm spectral region, along with luminescence at 1272 nm attributable to singlet molecular oxygen, were observed. A comprehensive kinetic analysis was performed, considering the rate constants of photophysical processes involving singlet oxygen in films with viburnum fruit extract on rough gold surfaces under conditions of sample saturation with molecular oxygen. Stable generation of singlet oxygen was achieved in the chitosan microfilms containing viburnum fruit extract. Practical significance. The findings of this study can be applied to biological methods for cancer treatment.
