Abstract :
Summary form only given.We present experiments performed under high-excitation conditions in films of methyl-substituted poly(para-phenylene) ladder-type polymer (m-LPPP): an electroluminescent material characterized by a high intrachain order, a narrow conjugation length distribution, and an emission in the blue spectral region. Photoluminescence (PL) and pump-probe experiments (with tunable probe) were performed with the second harmonic of a CPA Ti:sapphire laser as the excitation source.
