Among investigations of the conductive polymers, syntheses and development of regiospeciftc and melt-processible poly(thiophene-2,5-diyl) derivatives have had a significant effect on the applications in photonics and electronics. Moreover, with the advent of combinatorial techniques, a renaissance of soluble polymer studies should be observed because they can be processed with the HTE microfluidic devices. Therefore, in this work the poly(thiophene-2,5-diyl) system has been investigated as poly[3-(2- aroyloxyethyl)thiophene-co-3-alkylthiophene] or poly[3-(2-arylvinyl) thiophene-co-3-alkylthiophene] diad system. The aroyl or aryl chromophores act as an antenna and transfer energy of absorbed light by the saturated or 7t-bridge into the oligo(thiophene-2,5-diyl) nano-scale system acts as an acceptor and conductor. To enhance the solubility, a long-chain of the 3-alkyl substituent was introduced. Accordingly, over 25 new, conducting, soluble, regiospeciftc capolymers of the above structure was synthesized, and characterized with UV-Vis, FTIR, 1H and 13C NMR of their solutions and solid-state. Moreover, PL, DTG, magnetic susceptibility and charge-transfer properties of the native and doped copolymers as well as their stability towards environmental agents have systematically been studied. The 3-alkyl-chain was functionalized for the green solvent technology. The results show that the new copolymers have interesting and advantageous properties - particularly structural, luminescence and electrical - that allow their use for production of optoelectronic devices. The properties appear to depend on the copolymer structure / composition. Therefore, they may be tune and also are being developed for elaboration of selective electronic elements, especially sensors. (original abstract)

Opracowano syntezy nowych kopolimerów, takich jak poli[3-(2-aryloksyetylo)tiofen-2,5-diyl-co- 3-alkilotiofen-2,5-diyl] oraz poli[3-(2-arylowinylo)tiofen-2,5-diyl-co-3-alkilotiofen-2,5-diyl]. Zbadano ich właściwości fizykochemiczne. Polimery te absorbują światło za pomocą "arylowej" anteny, konwertują jego energię w impuls elektryczny, który może być dostarczony bezpośrednio do centrum procesu za pomocą politiofenowego nanoprzewodnika i w rezultacie może wywołać bardzo wydajne i selektywne przemiany fizyczne i/lub chemiczne. W artykule zaproponowano zastosowania tak generowanych przemian w procesach "zielonej chemii". (abstrakt oryginalny)
