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 -
Polymer networks have been produced in a variety of liquid crystal phases in cells without surface treatment. the liquid crystal / monomer mixtures are prepared using a ferroelectric liquid crystal and a diacrylate monomer. the polymerisation of the monomer is carried out by uv curing the mixture when it was kept in a specific phase which can be obtained by controlling the temperature of the ferroelectric liquid crystal. both the monomer and the polymer network will depress phase transition temperatures. the effects of the polymer network on the packing arrangement of the ferroelectric liquid crystal molecules are examined by means of optical microscopy. the molecular packing arrangement of the ferroelectric liquid crystal in a specific mesogenic phase is frozen on the formation of a polymer network in the ferroelectric liquid crystal in that phase. the existence of the diacrylate based polymer network can improve the electrooptical switching of the ferroelectric liquid crystal
在灌裝于未經表面處理的樣品盒內處于不同狀態的液晶中制備聚合體網路.液晶/單體混合物由鐵電液晶和雙丙烯酸單體製成.單體的聚合通過維持該混合物處在一定的液晶態的條件下經紫外線固化來完成.不同的液晶態可通過控制鐵電液晶的溫度來獲得.雙丙烯酸單體或聚合體網路的存在會導致鐵電液晶載體的相變溫度降低.通過光學顯微鏡可觀察聚合體網路對鐵電液晶分子組合排列的影響.結果發現:在某一液晶態中鐵電液晶分子的組合排列可被在該液晶態中聚合而成的聚合體網路所穩定，雙丙烯酸基聚合體網路的存在可改良鐵電液晶的電光開關特性
