In this work the first samples of polymeric semi-conductors of a new structure are produced. Their electric conductivity is of the order ∼10 -2 Ohm -1 . cm -1 and it increases with temperature. Their synthesis includes a stage of radiation grafting of a matrix-type on stretched polyamide films. Conducting molecular circuits in such materials include fragments with conjugated bonds and metal clusters. The alternation of these fragments is determined by the polyamide matrix.

IR electroluminescence was revealed in single-layer light-emitting diodes based on a type of electroactive polymer nanocomposites-electron-hole conducting aromatic polyimide and organic nanocrystalline particles of cyanine molecules, known as J-aggregates. These materials exhibit a very narrow emission band with a maximum at 815 nm. Dramatic increase of charge-carrier mobility was observed for these layers containing the J-aggregate nanocrystalline phase.

Poly(3,3’-phthalidylidene-4,4’-biphenylilene) was investigated, for use as an electron-hole-transport layer in photovoltaic cells. The drift mobility of charge carriers decreased by one to two orders of magnitude when magnesium phthalocyanine dye molecules at 5 wt.% were dispersed into the polymer. The photovoltaic properties were studied for polymer-dye structures sandwiched between ITO and Al electrodes.
