Study on the Spectral Properties and Optical Limiting Performance of a New Fluorene Derivative
A new fluorene-based derivative with long conjugated structure is synthesized by the Heck reaction. The ultraviolet absorption and fluorescence spectrum are measured in four different polar solvents (petroleum ether, methylen echloride, ethyl acetate, DMF). The results show that the solvent polarity has certain effect on the UV absorption and fluorescence spectrum of the new compound, in certain details, the UV absorption and fluorescence spectrum red shift occurs with the increase of solvent polarity. Picosecond pulse laser whose excitation wavelength is 1064 nm is used to investigate the optical limiting of the new material. The experimental results show that the new material has a large three-photon absorption coefficient (γ=5.4×10-21 cm3/W2) and the three-photon absorption cross section 3=7.3×10-77 cm6·s2.
