The behavior of a new charge transfer complex N-hexadecylpyridinium-Cd (dmi
t)(2) at the air-water interface was investigated. The Langmuir-Blodgett (L
B) films were fabricated from the floating layers with or without arachidic
acid (AA) as a matrix. Compared with the pure complex, the 1:1 mixture can
form better Y-type films, which was proved by W-visible spectra and small-
angle X-ray diffraction patterns. Conductivities of the LB films were measu
red using a two-probe method at room temperature. After iodine doping, the
maximum conductivities reached 1.6 S cm(-1) and 3.1x10(-1) S cm-l for LB fi
lms of the pure complex and 1:1 mixture with AA, respectively. The spectral
changes during oxidation of the LB films were also examined. (C) 2000 Else
