UV LASER INITIATED STEREOSELECTIVE HOMOGENEOUS CATALYSIS POLYMERIZATION OF PHENYLACETYLENE
摘要:
In this paper, the stereoselective homogeneous catalysis polymerization of phenylacetylene by using two kinds of catalysts W(CO)5CH3I and W(CO)4I2 produced from UV laser photolysis of W (CO)6 in CH3I, I2—C6H6 and CHI3—C6H6 respectively was studied. The effects of laser energy, laser irradiation time and lifetime of catalyst on the polymerization of phenylacetylene were discussed. The photoproducts of W (CO)6 in CH3I, I2—C6H6 and CHI3—C6I6 were determined by IR spectra. The structures of polyphenylacetylene obtained by W(CO)5CH3I and W(CO)4I2 catalysts were characterized by IR spectra and 1 NMR spectra.
