✦ Synopsis


Second-order molecular hyperpolarizabilities (Ξ³) of four tetraphenylchlorin derivatives were measured by the Z -scan technique at 784 nm in the off-resonant region and the enhancement in the hyperpolarizabilities of these derivatives in comparison to the regular porphyrins with the same external side-groups is explained on the basis of the difference in their Q-band oscillator strengths.

## Abstract Poly(1,4‐phenylenevinylene) (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
