Study on Spectral Properties of a New Tricyanofuran Derivative
A new D-π-A type of tricyanofuran derivative (DCDHF-2-V) with a novel electron donor was synthesized. The heterocyclic compound-in-poly (methymethacrylate) (PMMA) film was then fabricated by means of the spin-coating method, and its photophysical properties in the solutions and thin film were investigated by UV-vis absorption spectra and fluorescence emission spectra. The results show that compared with the absorption spectrum of the compound in solution, the absorption maximum of the film is shifted to some extent, and the absorption band becomes broader. It is found that the maximum peak wavelength of fluorescence spectra, fluorescence quantum yield, and Stocks shift change along with the variation of the polarity of solvent. Moreover, the difference in the dipole moment between the ground and excited states was obtained to be 35.68×10-30 C·m. And the second-order polarizability value of DCDHF-2-V was estimated based on the quantum-mechanical two-level model and its calculated value was 3323.4×10-40 m4/V at the wavelength of 1064 nm.
