In Chapter 5, photo-induced absorption is used to study the intersystem crossing from singlet to triplet states of two polyfluorenes after doped with Ir-complex. It is found that the triplet exciton lifetime of PFs is reduced by the dopants. But instead of decreasing, the population density of PF triplet exciton increases by almost one order of magnitude. The finding shows that the ISC rate can increase over 100 times due to the spin-orbital interaction with the Ir ions.

第五章以光诱发吸收光谱技术研究两种聚芴高分子掺杂绿光铱错合物后，聚芴的单重态到三重态的内部系统转换效率的改变；研究发现在掺杂后，聚芴的三重态生命期减短，但出乎意料的是其三重态的态密度并没有随之降低反而有一个数量级的增加，其原因为单重态到三重态的内部系统转换受铱错合物的影响效率增加了100倍。

The conjugated rings affect the bioactivity most. Antitumor activity was greatly improved through changing the phenyl ring with a naphthyl ring.

下端共轭环对活性的影响最大，将下端的共轭环扩大的过程中，将苯环改为萘环，其活性提高了近一个数量级。

For TRO there are a little surfacatants whose effect are not good.In this paper,content of sulfonates and composition of alkyl are decided through right design ;under control reaction conditions different alkylbenzene sulfonates are synthesized;Polyreaction catalyst is developed .non-straight high carbon olefine are made through C9-C12 Polyreaction technolgy;clear composition alkylkenzene is sulfanated in falling-film reactor by SO,product can be adjusted,recipe of the surfacate can be used for super-low interfacialtension with Daqing oil -10-3-10-4mN/m,and stablity is good too.According to method issued by Daqing Develop and Explore Research institute,EOR is over 20% in natural core .

本文研究通过烷基苯磺酸盐组成的正确设计，确定了磺酸盐的当量范围和烷基碳数组成和分布；通过对烷基化条件控制，设计合成了不同碳数的直链和支链烷基苯及烷基二甲苯，并用于制备了相应的烷基苯磺酸盐；研制出了新型的烯烃叠合络合催化剂，采用C_9、C_(12)支链烯烃叠合工艺合成了更高碳数的支链烯烃，并进一步合成出相应的烷基苯和烷基二甲苯；以SO_3为磺化剂，通过对磺化条件的选择和控制，采用已知组成的烷基苯混合物进行膜式磺化反应，使合成工艺得以简化；所得磺酸盐组成确定并且可控，最终配方可与大庆原油形成超低界面张力，达10~3～10~(-4)mN/m数量级，且稳定性良好；以合成的烷基苯磺酸盐为主体形成了三元复合驱配方，室内驱油模拟实验表明，按照大庆研究院对复合驱体系活性剂的评价方法，在天然岩芯上的驱油效率在20％以上。
