Two-photon absorption in perylene and its derivative
Two-photon absorption and two-photon absorption cross-section of perylene and its derivative dissolved in chloroform and dimethyl sulfoxide were estimated using nonlinear transmission technique. It was found that the studied materials exhibit high two-photon absorption process in ps regime. The value of two-photon absorption cross-section of perylene derivative is higher by a factor of 3 compared to perylene. This fact could be due to longer conjugation length of molecule. However, no solvent effect was observed.
