We have measured resonant third-order optical nonlinearities of organic nanoparticles. Five kinds of near-infrared dyes, silicon 2,3-naphthalocyanine bis(trihexysiloxide) (dye 1), methylsilicon (IV) phthalocyanine chloride (dye 2), 2,3-naphthalocyanine (dye 3), 2,4-di-3-guaiazulenyl-1,3-dihydroxycyclobutendiyliumdihydroxide, bis(inner salt) (dye 4), and 1,3-bis-[(3,3-dimethylindolin-2-ylidene)-methyl] croconium (dye 5) were used to prepare organic nanoparticles. The values of the electronic component of the molecular hyperpolarizability, γe, were determined to be ca. 1.9 × 10-29 esu, ca. 1.9 × 10-30 esu, ca. 3.4 × 10-31 esu, ca. 2.1 × 10-30 esu, and ca. 3.0 × 10-30 esu, for dyes 1, 2, 3, 4, and 5, respectively.
