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

We investigated the structure of BDN(bis(4-diethylaminodithiobenzil) Nickel )-SOH(Stearyl alcohol) Langmuir-Blodgett films using small angle X-ray diff raction and polarized FTIR spectroscopy. The results show that the microcry stal domains formed on the surface of LB film resemble a well-laminated per iodic structure with a molecular spacing of 2.56 nm. Meanwhile, the tilted angles of the molecules of SOH and BDN are about 30 degrees, referring to t he normal direction of the sample surface, as determined by our XRD and FTI R studies.
