Abstract

A luminescent main chain donor–π–acceptor‐type polymer (4) was prepared via organometallic polycondensation reaction followed by post modification. With both electron‐rich amine and electron‐deficient borane moieties embedded in the main chain, 4 exhibits an interesting ambipolar character: it can be reduced and oxidized electrochemically at moderate potentials and shows a strong solvatochromic effect in the emission spectra. Complexation studies show that 4 selectively binds to fluoride and cyanide; quantitative titration with cyanide reveals a two‐step binding process.
