Preparation, Linear Spectrum and Nonlinear Two-photon Absorption Properties of Fluorenone Derivative Containing 4-Methoxystyrene

摘要

The nonlinear optics is a new and important branch in the field of optical physics. Compared with the traditional optics, the nonlinear optics can produce many special phenomena such as frequency doubling, optical limiting, two-photon absorption and so on. Therefore, it has great potential for application in high technology. In this research, A novel fluorenone derivative containing 4-methoxystyrene with symmetric structure D-π-A-π-D is prepared using the heck reaction, namely, 2, 7-bis((E)-4-methoxystyryl)-9H-fluoren-9-one(W-J-B). The linear spectrum including ultraviolet absorption spectra and one-photon fluorescence emission spectra are measured, the nonlinear two-photon fluorescence emission spectra is researched in different excitation wavelength and powers. The results exhibit that this novel organic material has good two-photon absorption performance and nonlinear optical effect, which has potential application prospect in the field of new and high technology such as frequency up-conversion, 3D micro-fabrication, photodynamic therapy, 3D optical data storage and so on.
