Synthesis of monodisperse spiro-bridged ladder-type oligo-p-phenylenes.
Monodisperse spiro-bridged ladder-type oligo-p-phenylenes, which have very rigid backbones, exhibited intensive emissions with very small Stocks shifts, displayed very good color stability upon thermo-oxidation, and were synthesized by Suzuki cross-coupling, oxidation, and BF3.ether-catalyzed cyclization reactions.
