Photo-Induced Reaction Dynamics in Poly(di-n-hexylsilylene) by Excimer Laser Flash Photolysis

KrF excimer laser induced photo-dissociation reaction was observed for poly(di-n-hexylsilylene) (PDHS) in several solvents at room temperature by using transient absorption spectroscopy technique within the wavelength range at 340-1600 nm. Transient absorption strongly depended on solvents suggestin...

Zusammenfassung:	KrF excimer laser induced photo-dissociation reaction was observed for poly(di-n-hexylsilylene) (PDHS) in several solvents at room temperature by using transient absorption spectroscopy technique within the wavelength range at 340-1600 nm. Transient absorption strongly depended on solvents suggesting that observed near UV absorption was ascribed to polysilylated silyl radicals in cyclohexane and tetrahydrofran (THF), and electron photoejection was also observed in CH2Cl2 giving radical cations of PDHS.
