Novel conjugated polyelectrolytes based on polythiophene bearing phosphonium side groups

Popis výsledku v původním jazyce

The synthesis and photophysical properties of poly{3[6-(triethylphosphonium)hexyl]-thiophene-2,5-diyl bromide) and poly{3-[6-(triphenylphosphonium)hexyl]-thiophene2,5-diyl bromide) are reported in the present contribution. Three various polymer precursors (poly[3-(6-bromohexyl)thiophene-2,5-diyl]s) with molecular weights 7.2, 11.8 and 13.2 kg mol(-1) respectively and head to tail regioregularity from 62% to 94% were prepared and consecutively transformed into the corresponding polyelectrolytes by a simple quatemization reaction with appropriate phosphines. Synthesized polyelectrolytes exhibited solvatochromism. Detailed aggregation experiments via changing water/DMSO ratio have been performed. Photoluminiscence spectra of the polyelectrolyte solutions indicate that the emission maxima are red -shifted gradually with the increasing solvent polarity. Fluorescence quenching has been studied by interaction with model quenchers: K-4[Fe(CN)(6)] and K-3[Fe(CN)(6)] in water using Stern-Volmer methodology.
