The third-order optical susceptibilities |x^<(3)>_<1111>(-3ω;ω,ω,ω)| for spin-coated films of free-base (H_2) and MnCl-octaethyl[18]porphyrins, and N,N',N",N‴-tetramethyl-octaethyl[26]porphyrin-bistrifluoroacetate are determined by optical third-harmonic generation measurements at a wavelength of 1907 nm. The |x^<(3)>| values are 1.9 x 10^<-12>,2.6 x 10^<-12>, and 1.0 x 10^<-11> esu for H_2-[18]porphyrin, MnCl-[18]porphyrin, and [26]porphyrin, respectively. The enhancement of third-order nonlinear properties in macrocyclic compounds is discussed in terms of an extended π-electron system.
