Beschreibungen/Notizen

• Second‐order molecular hyperpolarizabilities (γ) 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.
