In this study aldylencdithiomethylene Malonic acid acts as the main coordination agents and compound iron ion have been synthesized by the means of solution, As a result ,the 1D polymer is obtained.

本论文采用常规的溶液合成方法，首先设计合成了一个以含有二硫缩烯酮结构的丙二酸类配体和过渡金属铁离子的单核配合物，再以此单核配合物作为配体设计合成了三个异多核配合物和配位聚合物。

It has been reported that the leaf and root extracts of Petasites hybridus relieve gastrointestinal pain, lung-disease such as asthma and cough, as well as spasms of the urogenital-tract, and even suppress the proliferation of human T24 bladder carcinoma cells. In 2000, S-petasin had been found to decrease the testosteron releasing by rat testicular interstitial cells.

此植物体及其萃取物应用在治疗使用上已约有两千年的历史，在1994年的研究中指出其粹取物对於人类膀胱癌细胞株（T24）具有抗增殖的效果，且於2000年，本实验室研究发现其粹取物-硫蜂斗菜素具有抑制大鼠间质细胞分泌睪固酮的效用，然而它对於人类前列腺癌细胞株是否也会造成毒杀效应，目前则尚未有文献探讨。

In this research, two novel compounds in which alkylenedithiomethylene Malonic acid act as the main coordination agents and the compounds containing N atom (such as pyridine, Phenanthroline Ethanediamine and 4,4'-Bipyridinyl) act as the associating coordination agents have been synthesized by the means of solution and solid-liquid diffusing reactions. 9 coordination complexes and polymers have been designed and synthesized in which the transition metals Cu and Zn acted as the centre ions. These compounds have been characterized by X-ray single crystal diffraction analysis, and some properties of them have been tested and analyzed.

本论文设计合成了两种结构新颖的含有二硫缩烯酮结构的丙二酸类化合物，以此为主要配体，以含氮化合物(吡啶、邻菲罗啉、乙二胺和4，4'-联吡啶)为辅助配体，采用常规溶液合成和固-液相扩散等方法，设计合成了9个过渡金属Cu和Zn离子配合物和配位聚合物，采用单晶X-射线衍射等技术对晶体结构表征，并对其部分性质进行了测试和分析。

Polymer substrates with dormant groups on the surface were prepared through the recombination of ITX pinacol radicals and surface radicals generated by the abstract hydrogen reaction.The influence of light intensity,irradiation time,concentration of ITX solution and polymer substrates to the dormant group density was investigated respectively.

论文取得的主要结果如下：1、利用夺氢型光引发剂异丙基硫杂蒽酮的夺氢-偶合光化学反应，将ITX嚬哪醇自由基固定到基材表面，制得了表面偶合有休眠基的聚合物基材。

The six polyhydroxy amine-linked thioxanthones have not been found in literature.

此六个多羟基胺连硫杂蒽酮衍生物均未见文献报道。

It is suggests that, in formulating of photocurable self-emulsifying coatings, Darocur 2959 and polyhydroxy amine-linked thioxanthones should be employed as photoinitiators other than those with high water-solubility, such as WB 4759

证明了在乳化型等水分散性光固化涂料中，不宜使用亲水性太强的光引发剂，而应选用水溶性相对较小的2959或多羟基胺连硫杂蒽酮等。

It can be used in spreading the two-component polysulphide sealant and the silicon sealant when manufacture the insulating glass and the curtain wall glass.

该机是制作槽铝式中空玻璃和幕墙玻璃时，用于双组份聚硫密封胶和双组份硅酮胶结构的施工

The last part is concerning the new application of dialkyl-substituted propargylic dithioacetals.

第三部分则是双烷基取代炔丙基硫缩酮的新型态反应。

However, alkyl-substituted propargylic dithioacetals could be synthesized by the displacement reaction of the corresponding terminal alkynes with alkyl iodides.

烷基取代的炔丙基硫缩酮衍生物，则能利用相对应的末端炔和碘烷亲电基进行取代反应所获得。

In previous results, Alkyl substituted propargylic dithioacetals treating with butyl lithium then were allowed to react with carbonyl compounds to form homopropargylic alcohol with high yields and highly regioselective.

在本实验室先前的研究中发现，烷基取代炔丙基硫缩酮与正丁基锂进行开环反应后，若是与羰基化合物反应，能够以高产率、具位向选择性的生成高炔丙基醇。
