炔丙基胺類化合物的合成Abstract : polyphenylacetylenes were synthesized by rn ( nbd ) cl 2 and wcl6 / ph4sn catalyst systems in n2 at room temperature. polymers with high yield and high molecular weight were obtained. their structures were characterized by uv, ir, nmr and gpc, respectively. the fluorescence of the polymer solution with different concentration was investigated using variable excitation wavelength from uv to visible region. the relation between fluorescence and polymer structure was studied. the results showed that the molecular chain structure has great influence on fluorescence of the polymers. the emitting peak wavelength of fluorescence for the polymer of high stereoregularity is independent of solution concentration and excitation wavelength. the emitting peak wavelength of fluorescence for the polymer with disordered molecular chain arrangement varies with changing the solution concentration and excitation wavelength, and different emission sites in molecular chains and low emitting yield are shown. the measurement and analysis of fluorescence spectroscopy of polyphenylacetylenes may provide some useful information to judge the molecular chain arrangement in some conjugated polymers
文摘:使用有機金屬銠、金屬鎢/四苯基錫催化劑體系聚合苯乙炔，分別獲得了高產率和高分子量的聚苯乙炔.使用uv ， ir ， nmr ， gpc等分別對聚合物結構進行了表徵.採用不同波長的激發光對聚合物熒光性能進行研究，詳細分析了聚合物結構與熒光性能之間的關系.研究結果發現，不同聚合物結構對聚合物熒光性能產生很大影響，規整性高的聚合物，將有較高的發光量子效率；聚合物規整性差，將可能導致多個熒光發光結構點，其熒光強度降低.聚合物熒光光譜研究將對某些共軛聚合物結構的規整性分析提供一些有用的信息( 3 ) a testing system consisting of pressure transducers, data - collecting card, computer and electrical - ignition instrument was designed and a flammable gas cloud deflagration experimental system was developed. based on the orthodoxy experiments, the experiments was conducted on c2h2 - air flame acceleration resulted from hemispherical porous barriers in hemispherical gas cloud. the relations between the explosion overpressure and its influence factors were summarized
