摘要

Novel fluorene-based poly(aromatic diacetylene)s have been synthesized by CuCl-catalyzed oxidative coupling of aromatic diynes. New aromatic diynes 2

7-diethynyl-9

9-bis(triphenylamine)fluorene (M1) is synthesized by multistep reactions. The structures and properties of the polymers are characterized and evaluated by IR

NMR

TGA

photoluminescence (PL)

and cyclic voltammetry analyses. These polymers possess good thermal stability. All the polymers are completely soluble in common solvents such as toluene

THF

chloroform

and dichloromethane. The polymers exhibit strong blue photoluminescence in solution and green photoluminescence in the solid state. The polymer containing triphenylamine-substituted fluorene has lower oxidation potential (－5.45 eV) than the previous polyfluorenes (－5.80 eV).
