Two isomers of 3-methylindano[2,1-c]piperidine were isolated in the reduction of 3-methyl-2-azafluorene with sodium in alcohol. N-(-Hydroxyalkyl) derivatives of this heterocyclic system were obtainedTranslated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 666–668, May, 1972. 相似文献

Second-order non-linear optical polymers having photocrosslinkable moieties were synthesized by cationic polymerization of monomer (I) and monomer (II). The polymerization proceeded rapidly to give linear polymers in high yields. Monomer reactivity ratios were calculated to be r1 = 0.90 and r2 = 0.96 (r1r2 = 0.86), indicating that these monomers copolymerized through the almost ideal copolymerization mechanism. The photocrosslinking reaction of an equimolar copolymer film underwent the conversion of up to ca. 70% upon irradiation with a 500 W high-presure mercury lamp for 5 min. The electric field induced polar orientation of the chromophores (pendant 4-nitrophenyloxy groups) in a photocrosslinked polymer was stable for more than 10 days. This polymer exhibits a nonlinear coefficient d33 of 5.6 × 10-10 esu measured at a pumping wavelength of 1064 nm. 相似文献
