Studies on charge transfer properties from mixture of Schiff base and zinc complex in Langmuir-Blodgett film by UV-vis absorption and Fourier transform infrared spectroscopy.

A novel mixed Langmuir Blodgett (LB) film based on a 1:1 (molar ratio) mixture of a non-amphiphile complex (Et4N)2[Zn(dmit)2] (H2dmit = 4,5-dimercapto-1,3-dithiole-2-thione) and Schiff base amphiphile 2,4-dihydroxy-N-octadecylbenzylideneamine (SBC18) was constructed and characterized by Fourier transform infrared (FTIR) spectra and UV-vis electronic absorption spectra. After iodine was doped in situ, magnitude of charge transfer increases, which was demonstrated by FTIR and UV-vis absorption spectral analysis.
