Second-order molecular hyperpolarizabilities (ฮณ) 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 sid
