  • P22 Sonochemiluminescence of lucigenin using aliphatic amine as coreactants

抄録

Sonochemiluminescence (SCL) from aqueous solution of lucigenin (Luc2+) has been studied with using aliphatic amines, such as ethylamine, propylamine, dipropylamine, tripropylamine and trimethylamine (TEA) as coreactant. It is found that strong SCL was observed from oxygen saturated alkaline solution containing Luc2+ when small amount TEA was added into the solution. A possible pathway for Luc2+ SCL reaction is discussed. In the ultrasonic field, TEA can adsorb onto the cavitation bubble/solution interface where TEA is oxidized by OH• to form TEA•+ and subsequently produce a highly reducing TEA• from the deprotonation reaction of the TEA•+. TEA• is suggested to initiate the reduction reactions of Luc2+ and O2 and lead to the generation of Luc•+ and O2•-, respectively. The radical-radical coupling reaction between Luc•+ and O2•- is expected to initiate the light emission.
