Synthesis of Monodisperse Spiro-Bridged Ladder-Type Oligo-p-phenylenes
摘要:
[GRAPHICS]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.
