Structural characterization of BDN-SOH LB films using small angle XRD and Fourier transform IR spectroscopy

摘要

We investigated the structure of BDN(bis(4-diethylaminodithiobenzil) Nickel)-SOH(Stearyl alcohol)Langmuir-Blodgett films using small angle X-ray diffraction andpolarized FTIR spectroscopy. The results show that themicrocrystal domains formed on the surface of LB film resemble awell-laminated periodic structure with a molecular spacing of2.56nm. Meanwhile, the tilted angles of the molecules of SOH andBDN are about 30°, referring to the normal direction of thesample surface, as determined by our XRD and FTIR studies.
