Water‐soluble π‐conjugated polyfluorene bearing 6‐N₁‐hexylcytosine and 6‐trimethylammoniumhexyl side chains: Synthesis, chemical properties, and sensing ability for nucleoside and telomere DNA

Abstract

Water-soluble π-conjugated polyfluorene bearing 6-N 1 -cytosinehexyl and 6-trimethylammoniumhexyl bromide side chains, namely polymer-1, was synthesized by Suzuki polycondensation. The absorption onset wavelength (λ onset ) of the polymer was longer than that of the monomer and confirmed the presence of the π-conjugated system along the polymer chain. The cyclic voltamme-
