Electronic Structure of Polysilanes Studied by Femtosecond Laser Flash Photolysis

Abstract Transient absorption spectra were obtained in solution of poly(methylphenylsilylene) (PMPS) and poly(methyl-n-propylsilylene) (PMPrS) at room temperature in the wavelength range 340-500 nm, using femtosecond laser flash photosysis. Transient absorption bands in near UV region, were ascribed to exciton states.
