Paper Abstract

We present our results on the characterization of ultrafast excited state dynamics of two phthalocyanines in thin film form studied using femtosecond pump-probe technique. One was a symmetric Zinc phthalocyanine (SPc) while the other was an unsymmetrical Zinc phthalocyanine (USPc). The femtosecond (fs) pulses at 800 nm were characterized using a single shot autocorrelator. The pump probe measurements were carried out with 590/610 nm pulses emanating from an optical parametric amplifier. SPc demonstrated an excited lifetime of ~30 ps while the ASPc exhibited ~60 ps lifetime. The potential applications of these molecules are discussed briefly.
