摘要

The two-photon fluorescence excitation and optoacoustic spectra of red polyDCHD-HS in benzene solution at room temperature have been investigated in the 1600-750 nm excinting wavelength region (effective two-photon energy approx 1.55-3.31 eV). The spectra obtained by the two dettection techniques are of comparable accuracy, and the observed band profiles are in good agreement. Two electronic ban d systems have been observed and assigned to two-photon allowed A_g -> A_g transitions. Both A_g states are at energies higher than that of the strongly one-photon allowed 1B_u state. An estimate of the absolute two-photon absorptivity of polyDCHD-HS at 406.0 nm (approx 3.05 eV) is given by means of the optoacoustic method. Our results are discussed on the basis of the current theories on electronic states of #pi#-conjugated polymers and compared with reported data on these systems.
