中文摘要：
一单音代用品的 polyacetylene 和二代替 di 的 polyacetylenes 的光性质被调查了。每代替的 polyacetylenes 在方面链忍受一个 carbazole 单位。尽管有在他们的分子的结构的差别， dilute 答案(这些的 10 ~(-6) M ) 代替了的大约 1 × polyacetylenes 展览一样的吸收和深蓝的排出物(大约 360 nm ) 。有趣地，这些代替的 polyacetylenes 的吸收和排放系列类似于小分子 carbazole 的那些。当代替的 polyacetylenes 的集中增加 10 ~ 到大约 1 ×(-6) M，我们在大约 475 nm 检测了强烈蓝排出物。我们的结果显示吸收，深蓝的排放(大约 360 nm ) 和强烈蓝排放(大约 475 nm ) 在方面链从 carbazole 色基发源。
英文摘要：
The optical properties of one mono-substituted polyacetylene and two di-substituted polyacetylenes have been investigated. Each of the substituted polyacetylenes bears a carbazole unit in the side chain. In spite of the differences in their molecular structures, the dilute solutions（about 1 × 10^-6 M） of these substituted polyacetylenes exhibit the same absorptions and deep-blue emissions （about 360 nm）. Interestingly, the absorption and emission spectra of these substituted polyacetylenes are similar to those of the small molecule carbazole. As the concentration of the substituted polyacetylenes increases to about 1 × 10^-6 M, we have detected intense blue emissions at about 475 nm. Our results indicate that the absorption, the deep-blue emission（about 360nm） and the intense blue emission （about 475nm） originate from the carbazole chromophores in the side chain.
