摘要：

We present spectral evidence of the efficient photogeneration of tripler-state excitations in poly(3-alkylthiophene): P3AT, solutions, The steady-state photoinduced absorption spectra display a PIA band centered at 1.50 eV which is attributed to a dipole-allowed triplet-triplet transition. Photoexcitation of P3AT solutions containing C-60, results in an efficient energy transfer reaction and provides an estimate for the P3AT triplet-state energy of 1.57-1.72 eV.
