摘      要：Two new functional polyacetylenes bearing different azobenzene group, -{ HC=C[azo-N （CH3）CH2CH2OH] } n-, [poly（EHAB）; azo = 4,4＇-azobenzene] and - { HC=C[azo-N（CH3）CH2CH2O COC3H7]},-, [poly（EEAB）]} were prepared by [Rh（nbd）Cl]2-Et3N catalysts. Poly（EHAB） has poor solubility while poly（EEAB） can be dissolved in common solvent. The polymers were characterized by FHR, ^1H NMR, UV and GPC. The nonlinear optical property of the soluble poly（EEAB） was investigated with 8 ns width pulse at 532 nm by Z-scan technique. The results show that poly（EEAB） is endowed with the larger third-order nonlinear optical property.
