Abstract—Conducting polymeric form of the complex of Cu(II) with N,N'-bis(3-methoxysalicylidene)-1,3-
propylenediamine was obtained by the electrochemical method. X-ray photoelectron spectroscopy and electronic
absorption spectroscopy were used to characterize the starting substances and their polymeric forms. The invariance
of the charge state of copper in the oxidation-reduction of the polymer based on the complex of Cu(II) with
a Schiff base was substantiated.
The appearance and rapid development of a promising
ﬁ eld of modern chemistry, supramolecular chemistry
concerned with organized associations of saturated-
coordination species, is due to advances in modern basic
research and high technologies [1–3]. A particular place
in supramolecular chemistry belongs to electrically
conducting supramolecular structures—polymers based
on organometallic and complex compounds of transition
metals. As a rule, these are intensely colored substances
possessing a set of valuable properties. To these properties
belong redox conductivity of polymeric complexes,
photosensitivity, photo- and electrical activity, capacity
for electrocatalysis, and electrochromic properties.
Of particular importance from the standpoint of the
possible practical use are polymeric structures stable
against chemical and physical action, characterized by a
high rate of charge transport in the bulk of the solid phase.
Polymeric compounds satisfying these requirements,
including those based on complexes with Schiff bases,
can be regarded as promising materials for sensor,
chemotronic, photo- and electrocatalytic devices, and
solid-phase converters of luminous energy .
Previously, the method of electrochemical oxidation
has been employed to obtain polymers based on
complexes of transition metals with tetra- and bidentate
Schiff bases of the N
-, and NO-types [4–9].
This communication reports on synthesis of a new
complex of Cu(II) with a tetradentate Schiff base
of the N
msalpn-1,3), and of a con-
ducting polymer by electrochemical oxidation of
[Cumsalpn-1,3]. The starting substances (Fig. 1) and
the polymeric form of the complex [Cumsalpn-1,3] in
the oxidized and reduced states were characterized by
X-ray photoelectron spectroscopy (XPS) and electronic
