1,8-naphthalimide-based luminiscent probe for sensing of metal ions
Original language description
This work is focused on the synthesis and subsequent post-polymerization modification of highly regioregular polymer precursor poly[3-(6-bromohexyl)thiophene] (PHT-Br), prepared by nickelcatalyzed Grignard metathesis polymerization. Modification of PHT-Br into corresponding cationic polyelectrolytes using simple quaternization reaction with tributylamine or tributylphosphine respectively was used for introducing a functionality allowing sensing of selected metal ions in the environment. This procedura allowed preparation of luminescent conjugated polyelectrolyte bearing simultaneously both phosphonium and ammonium pendant groups in the same polymer main-chains. Transformation of pendant bromide groups into azides ones followed by Huisgen 2+3 dipolar cycloaddition ("click" reaction) with luminophore N-(prop- 1-yne-3-yl)-4-(morpholine-1-yl)-1,8-naphthalimide (NF) was used as a second approach. Luminescence quenching has been evaluated quantitatively using Stern-Volmer methodology using potassium ferrocyanide and ferricyanide as model pollutants.
