摘要：
A hyperbranched poly(aryleneethynylene) containing anthracene chromophore was synthesized by palladium-catalyzed cross-coupling reaction of 2,4,6-triiodophenyl 9-anthracenylcarboxylate with 9,9-bis[4-(2-propynyloxy)phenyl]-9H-fluorene. The structure and properties of the polymer are characterized and evaluated by NMR, IR, UV, PL and TGA analyses. The polymer is soluble in common organic solvents, possesses high thermal stability (T-d > 330 degrees C), and emits a strong blue light of 465 nm in both solution and solid states.
