摘要：

Laser flash photolysis of 2,4,6-triphenylpyrylium tetrafluoroborate in the presence of trans-stilbene, triphenylethylene, and tetraphenylethylene has been carried out in dichloromethane. It has been revealed that trans-stilbene radical cations form dimeric radical cations of trans-stilbene through a reaction with its neutral while the radical cations of triphenylethylene and tetraphenyl-ethylene do not. © 1990.
