The preparation of multilayered structures with polyconjugated systems
has been performed with a modified poly (3-alkylthiophene) containing
an oxygen atom in the side chain as reported in a previous paper [1].
The polymeric backbones in the obtained Langmuir-Blodgett structures
have been found to be oriented in the dipping direction and the conjug
ation length so far obtained is higher with respect to that previously
reported [ 1]. Alternated multilayered heterostructures formed by two
layers of a diacetylenic cadmium salt and one layer of the above-ment
ioned polymer has been prepared obtaining, after photopolymerization,
alternated heterostructure between poly-diacetylene and poly(3-alkylth
iophene), A preliminary investigation of the electronic behavior of th
is heterostructure is reported. (C) 1997 Elsevier Science S.A.
