The thirdarder microscopic hyperpolarizability y is calculated for finite bridged polymers of the form A-B-A-B-... using simple model Hamiltonians. Generally, the even-and odd-numbered chains show markedly different behavior, with the addition or subtraction of one chain unit resulting in a predicte
Au films of thickness ranging between 5 and 52 nm were prepared by sputtering on quartz substrates and their third-order nonlinear optical response was investigated by Optical Kerr effect (OKE) and Z-scan techniques using 532 nm, 35 ps laser pulses. All prepared films were characterized by XRD, AFM
## Abstract Poly(1,4βphenylenevinylene) (PPV) and its derivatives are readily processable and thermally stable polyconjugated polymers. Since PPV contains phenylene units, its structure can be easily altered and modified in the electronic structure. Moreover, PPV and the derivatives are easily prep
