Study of Synthesis and Optical Properties of Ferrocene Derivative Doped Polyimide Film
In view of the applications of ferrocene derivatives in photoelectric functional material, a new type ferrocene derivative,1-ferrocenyl-3-(4-dimethylamino phenyl)-c-2-alkene-1-ketone,with a big π -conjugate system is made of acetylferrocene and p-dimethylaminobenzaldehyde by condensation reaction. The compound is containing ferrocene ketone as an acceptor and dimethylamino phenyl as a donor. The structure of the compound is characterized by 1H-nudear magnetic resonance (NMR) spectra. Combining doctor blading and gradient temperature-elevating, the compound-doped polyimide thin film with mass fraction of 4% is prepared. The ultraviolet visible (UV-VIS) absorption spectra and optical constant of the thin film are determined by UV-VIS spectrophotometer and the transmission spectrum method, respectively. The nonlinear optical property of the thin film is studied using Z-scan technique with 30 ps pulses at 1064 nm. The value of the third-order nonlinear susceptibility of the thin film is 1.0375×10-11 esu. It is better than optical fiber by three orders of magnitude, so it can be used in the production of optoelectronic devices.
