Two-photon absorption three-dimensional optical data storage with novel anthracene derivative

Anthracene derivative is one of the important two photon absorption materials. In this work, novel symmetric-type D- π-D anthracene derivative, 2, 6 - di- substituted anthracene chromophore with 4-methylstyrene has been synthesized via Heck reaction. The two-photon absorption (TPA) fluorescence emission property and TPA absorption coefficient are investigated by Sapphire femtosecond laser pulses at the wavelength of 800nm, repetition rate of 1 KHz and pulse width of 120fs, in an attempt to obtain the TPA cross-sections of this compound (σfilm=695.8×10–50cm4s/photon). Finally, Three-dimensional (3D) optical data storage experiments are carried out and realized by two-photon absorption with 800nm-fs laser in the compound films.
