“…For a large number of organic semiconductors of different classes, we have experimentally established that films with a stable structure can be obtained if, after preparation, they are submitted to a heat treatment [13,18,28]. This consists of several successive heatings and coolings within a certain temperature range, DT, characteristics for each compound.…”

“…The study of these dependences during the heat treatment may offer very useful information on the processes taking place in the respective films [13,17,18,21]. We have experimentally established that the shape of the lns = f(10 3 /T) curves during heat treatment depends on the compound nature, film thickness and conditions of film preparation.…”

The investigated compounds are some derivatives of orthotolidin-N,N 0 -bis (4-aminobenzene-2-sulphonic) acid. The temperature dependences of the electrical conductivity and Seebeck coefficient are studied on the thin films deposited from dimethylformamide solution onto glass substrates. It is known that the investigated compounds have typical semiconducting properties. The values of some important parameters of the films (thermal activation energy of electrical conduction, concentrations and mobilities of charge carriers) have been determined. The correlations between some of these parameters and molecular structure of the respective compounds are discussed.

ABSTRACT:The studied polymers (chelate modified polysulfones) have been prepared by the polycondensation reaction between chloro-end-capped polysulfones and bis(2,4-dihydroxybenzaldehyde)Cu 2ϩ in the dymethyl sulfoxide/dichlormethane system, in the presence of an aqueous sodium hydroxide solution. The temperature dependence of electrical conductivity and Seebeck coefficient of the respective polymers was investigated using thin-film samples, deposited from chloroform solutions onto glass substrates. The polymers under study have typical semiconducting properties. The values of some characteristic parameters of the investigated polymers (for example, activation energy of electrical conduction, ratio of carrier mobilities, etc.) have been determined. The nature of the electrical conduction mechanism is discussed. The values of the optical bandgap energy are determined from the absorption spectra.

The synthesis and the study of DC electrical transport properties (electrical conductivity, r, and Seebeck coefficient, S) as a function of temperature of some recently synthesized nylon 6/12 copolymers with 0, 5, 10, 20, 30, and 50 wt % laurolactam (LL), respectively, are reported. Nylons were obtained by rotational molding via the anionic activated copolymerization of e-caprolactam and LL. As evidenced by XRD analyses, they are semicrystalline. The temperature dependences of r and S are typical for polycrystalline semiconducting (p-type) materials. The activation energy of electrical conduction lay in the range 0.79-1.22 eV, while the ratio of charge carrier mobilities ranged between 0.53 and 0.77. V V C 2007 Wiley Periodicals, Inc.
