Synthesis and photophysical and electroluminescent properties of poly(1,4-phenylene?ethynylene)-alt-poly(1,4-phenylene?vinylene)s with various dissymmetric substitution of alkoxy side chains

Popis výsledku v původním jazyce

The synthesis and characterization of a set of conjugated polymers, poly(1,4-phenylene?ethynylene)-alt-poly(1,4-phenylene?vinylene)s (PPE?PPVs), with a dissymmetrical configuration (partial or total) of alkoxy side chains is reported. Five new polymers bearing octyloxy and/or octadecyloxy side chains at the phenylene?ethynylene and phenylene?vinylene segments, respectively, were obtained. Two symmetrical substituted polymers were used for comparison. Polymers with weight-average molecular weight, Mw, upto 430000 g/mol and degree of polymerization between 17 and 322 were obtained by a Horner?Wadsworth?Emmons olefination polycondensation reaction of the respective luminophoric dialdehydes and bisphosphonates. As expected, identical conjugated backbonesin all polymers results in very similar photophysical response in dilute solution, with high fluorescence quantum yields between 50% and 80%. In contrast, the thin film properties are dependent on the combinatorial effects of side chain c
