摘要

After tentative ring-opening cross metathesis (ROCM) of endo-bicyclo[3.2.0]hept-6-en-3-yl 4-bromobenzoate with PhCH＝CH2 initiated by (Cy3P)2Cl2Ru＝CHPh in CH2Cl2

ring-opening metathesis polymerization (ROMP) of a series of endo-bicyclo[3.2.0]hept-6-en-3-yl benzoates was achieved under the same conditions

furnishing a variety of the corresponding polymers. Then some of them were selected to hydrogenate the C＝C double bonds in their backbone with p-tosylhydrazide

affording saturated and thus more flexible polymers. All of these polymers were well characterized by spectroscopic means including GPC

UV-Vis

NMR and IR

based on which the tacticity of these polymers was investigated together with nonlinear optical (electric-field-induced second-harmonic generation

EFISH)) analysis.
