摘要：
Based on photoelectron forwarding-scattering analysis, we present a new method using angle-resolved XPS to investigate the molecular packing structure of Langmuir-Blodgett (LB) films and self-assembled monolayers (SAMs). It was found that the average tilt angle with surface normal of a bis(4-diethyannodithiobenzil)nickel (BDN) molecule is about 40 degrees for the BDN-SA (stearyl alcohol) LB films, which is in agreement with the results of FTIR. The thickness and orientation of the molecular for 12-alkyl thiols SAMs on gold substrate were also estimated by using ARXPS. Estimated tilt angle with surface normal for 12-alkyl thiols molecule is about 30 degrees, which was confirmed by other literature results. (C) 1999 Elsevier Science B.V. All rights reserved.
