A series of 5 ' -phenyl-m-terphenyl carboxylic acid (PTCA) derivatives with
methyl, chloro, and fluoro substituents at both side phenyl rings have bee
n synthesized and characterized as Langmuir monolayers at the air/water int
erface. A comparative analysis, based on the surface pressure and electric
surface potential measurements under a variety of experimental conditions,
is complemented with BAM images. (C) 2001 Academic Press.
