V. Hartmann et al., UV/Vis and SFM studies on Langmuir monolayers and Langmuir-Blodgett films of 16-mer aniline and o-pentadecylaniline blends, MAT SCI E C, 8-9, 1999, pp. 425-429
The synthesis of a new amphiphilic blend of aniline, between a 16-mer oligo
aniline and o-pentadecylaniline (oPA), in molecular films is reported and i
ts morphology and UV/Vis absorption properties are characterized. The blend
forms stable Langmuir monolayers at the air/water interface and successful
deposition into Langmuir-Blodgett (LB) films was achieved by vertical dipp
ing. By preparing Langmuir monolayers on acidic subphases containing peroxo
disulfate. it was straightforward to polymerize the oligomer-monomer mixtur
e. Deposited LB samples exhibited molecularly smooth surfaces, as determine
d by scanning force microscopy (SFM). The electrooptical properties of mono
- and multilayers of 16-mer aniline/oPA mixtures and the polymerized blend
were analyzed by UV/Vis spectroscopy. (C) 1999 Elsevier Science S.A. All ri
