Abstract

Ultraviolet-visible and FT-IR spectroscopy have been applied to monitor molecular re-arrangement in Langmuir-Blodgett (LB) films of 2-pentadecyl-7,7,8,8-tetracyanoquinodimethane (C15TCNQ) prepared under the surface pressure of 5 and 2 mN/m and in those of C15TCNQ deposited on LB films of deuterated stearic acid (SA-d35). It was found that the molecular re-arrangement can be controlled both by adjusting the packing density of C15TCNQ and by changing the nature of the substrate surface.
