摘要

正

New hyperbranched poly（aryleneethynylene）s containing carbazole moieties are synthesized in high yields（up to 87%）by polycyclotrimerization of 3

6-bis（4-ethynylphenyl）-9-octylcarbazole and its copolymerization with 1-octyne catalyzed by CpCo（CO）

in THF.The structures and properties of the polymers are characterized and evaluated by IR

NMR

TGA

photoluminescence

and cyclic voltammetry analyses.All the polymers are soluble in common organic solvents and show outstanding thermal stability（≥430℃）.They graphitize in high yields（up to 79%）when pyrolyzed at 800℃. Upon photoexcitation

the polymers emit a strong deep blue light of ca.400 nm with quantum yields larger than 60%.
