Electrical conductivity and photoconductivity of films of composites based on poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene] with additions of zinc octabutyl phthalocyanine and C60

“…Such characteristics of Pc Bu Zn can be explained by its intraionic molecular structure and by the position of the energies of the molecular orbitals in relation to those in MEH-PPV and C 60 , which frequently explains the photogeneration and recombination characteristics of intraionic organic dyes and metal complexes [6,10,11]. As a result of the investigations it is possible to draw the following conclusions.…”

“…In order to increase the probability of the separation of geminal EHPs or to increase the probability of the formation of singlet EHPs during bimolecular recombination it is necessary to create conditions for the transport of both holes and electrons. The transport of electrons in the CF based on MEH-PPV with hole-type conductivity can be secured by the introduction of acceptors into the composition of the CF [10,11]. However, the electro-and photoconducting characteristics of composite films based on MEH-PPV with additions of metal-containing organic dyes and acceptors have not been studied.…”

Photoconductivity of films of aromatic polyimides with addition of ionic polymethyne dyestuffs

“…The problem of sensitization of the electron-hole conductivity of polyimides to create polymeric photoelectric converters of solar energy is a real problem, but it has not been sufficiently studied in the literature. The objective of the present work was to investigate the photoconductive properties of polymer films based on the aromatic compound PI6.0 with the addition of 1mass % of cationic (Dye 1) and anionic (Dye 2) polymethyne dyes, the first of which was capable of photogeneration of holes [8,9] and the second of electrons [8,10], and also to establish the possibility of photogeneration of holes and electrons in the PI polymer film.…”

“…PI6.0 was prepared by polycondensation [2], M n = (3-6)·10 4 , T g = 240°C. The procedure of preparing the samples, the measurement of the optical density spectra (D) in samples with a free polymer film surface and the density of the stationary photocurrent (j PH ) in samples with sandwich structure on irradiation with light from the SnO 2 : In 2 O 3 conducting layer are described elsewhere [9]. The thickness of the polymer film was 2-3 mm.…”

“…The most widespread photothermoplastic media for hologram recording are based on poly( N -epoxypropylcarbazole) (PEPC) films doped with organic acceptors or dyes [2][3][4]. Intermolecular charge transfer complexes (CTC) or dye molecules are used as light absorption centers at the radiation wavelength of an appropriate laser and photogeneration centers of charge carriers (charge pairs) in such films.…”
