Efficient Three-photon Excited Deep Blue Photoluminescence And Lasing Of Diphenylamino And 1,2,4-triazole Endcapped Oligofluorenes

摘要

Multiphoton absorption, in particular two-photon and three-photon absorption, has drawn considerable interest over the years because of its potential applications in various optoelectronics and photonics as well as the fundamental physics of nonlinear optics (NLO). Owing to the use of the longer wavelength excitation source and the characteristics of the intensity-dependence of the multiphoton absorption process, the multiphoton absorption offers many advantages for the technological applications of high capacity data storage, three-dimensional microfabrication, biological imaging, photodynamic therapy, and frequency up-converted lasing. Despite significant progress in developing organic molecules with large two-photon absorption (TPA) properties over the past decade, the study for structure-three-photon absorption property correlation of organic molecules is rather limited.
