摘要：

The synthesis of mostly new acetylenes, R1C CR2, (R-1=4-t-butylphenyl; R-2 4-t-butylphenyl; 4-[(t-butyl)(diphenyl) silyloxy] phenyl; 1-naphthyl; 2-naphthyl; 9-anthryl) is reported. Their UV-vis characteristics are discussed in comparison to the results of TD-DFT calculations. R1C CR2 (except for R-2=9-anthryl) give polyacetylenic polymers-[C(R-1)=C(R-2)]-(n), insoluble if R-1=R-2 and well soluble if R-1 not equal R-2 in polymerization with TaCl5/SnBu4. Polymerizability increases with increasing monomer triple bond accessibility for the catalyst. The photoluminescence yield of the soluble polymers rises in the R-2 order: 1-naphthyl < 2-naphthyl < 4-[(t-butyl)(diphenyl)-silyloxy] phenyl.
