A novel high molecular weight functional polyacetylene bearing oxadiazole group as a pendant, poly{4-[2-(4-octoxyphenyl)- 1,3,4-oxadiazolyl]-benzenyloxypropynylene}, was synthesized by [Rh(nbd)Cl]2-Et3N catalyst. The polymer was soluble in common organic solvents such as CHCl3 and THF. The structures and properties of monomer and polymer were characterized and evaluated with FTIR, NMR, UV, TGA, GPC, and CV, respectively. The results show that the polymer possesses high thermal stability and well electron-injection property. 展开更多

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(nb... 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. 展开更多

While WC16-Ph4Sn is a poor catalyst for the polymerization of l-phenyl-butyne (PB) at room temperature, it effectively polymerizes PB in the presence of C60, giving high molecular weight polymers in high yields. The polymer is soluble in THF and chloroform and spectroscopic analysis reveals that Coo has copolymerized with PB. Thus, C60 plays dual roles of comonomer and cocatalyst in the acetylene polymerization. The copolymers strongly attenuate 532-nm laser pulses, whose limiting performance is superior to that of parent 展开更多
