本课题通过引入甲基丙烯酸(2-N， N-二乙胺基)乙酯嵌段，采用室温原子转移自由基聚合，合成出分子量分布窄的具有自催化和自引发行为的甲基丙烯酸缩水甘油酯基二嵌段和三嵌段共聚物。

This research is taking sea perch as the material, and cloning the Syntaxin 1B gene. After extracting RNA from sea perch tissue, we gained the first chain of cDNA by RT-PCR. Then designing a pair of primers according to the sequence of Syntaxin 1B from other organism. Based on the first chain of cDNA cloned from sea perch, the partial sequence of Syntaxin 1B gene is been cloned by using TD-PCR and we received the 751bp fragment at last.

本实验从鲈鱼脑组织中提取总RNA，通过反转录得到cDNA第一条链，根据已克隆出的其它生物的Syntaxin 1B基因序列，设计并合成引物，在妒鱼syntaxin1B基因部分序列克隆与分析 cDNA第一条链的基础上使用降落PCR，进行体外扩增妒鱼 Syntaxin IB基因的部分序列，得到长度为75 lbP的片断，在胶中洗脱下该片段，与pMD 18一T载体链接，转化入感受态细胞，挑取阳性克隆扩大培养，提取质粒，经HindIH和x一gaH两内切酶消化得到75 1 bp的片断，证明链接成功。

Fluorescence emission spectra and UV absorb spectra analysis have been undertaken to test the influence of solvent polarity on the lowest excited singlet state of the tertiary amines. The absorption maxima were red-shafted slightly, and the emission maxima were red-shafted strongly, which showed all of the three compounds were found to be essentiallyππ* in character, which makes for the formation of triplet-exciplex state and the subsequent reactions,?known as photo-reduction and hydrogen-abstraction.

本文借助光谱检测的手段测试了新合成的增感剂的光物理化学性能，利用荧光发射光谱和紫外吸收光谱测试了溶剂极性对叔胺的最低激发单重态的影响，实验结果表明叔胺的紫外最大吸收波长随溶剂极性的增强产生轻微的红移，荧光最大发射波长随溶剂极性的增强产生明显的红移，表明三种叔胺的最低激发单重态具有ππ*跃迁的特性，这对于激态复合物的生成以及其后的光致还原反应和提氢反应的发生都非常有利。
