Abstract
The regioregular polyalkylthiophene reported in this contribution has been electrochemically synthesised startingfrom a 3,4-bis-methoxyacetyl-terthiophene and carefully characterised. Photoluminescence analysis gave, both in solutionand in films, very appreciable quantum yield values and LED devices realised with Ca cathode provided a valueof red electroluminescence comparable with those of regioregular poly(3-alkylthiophene)s in the monolayer activematerial architecture, while if a blend with poly-N-vinylcarbazole and 2-(4-t-butyl-phenyl)-5-(4-biphenyl)-1,3,4-oxadiazoleconstitutes the active layer a white emission is observed.File in questo prodotto:
