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]}n-, [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 FTIR, 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.
