Development of New Packing Materials in Chromatography Based on Molecular Recognition Concept

在本项目中，介绍了三种基本方法来提出、设计、合成和评价一种新的固定相，该固定相可以为多环芳烃(PAHs)和富勒烯的分离提供良好的拆分和选择性。这些步骤是基于分子识别机制的。对于多环芳烃，溶质是二维分子或立体大分子。首先，我们对易获得的用于分离多环芳烃和富勒烯的消耗臭氧层物质固定相进行了评估，其结果为我们设计新的固定相以提高选择性和性能提供了基本的理解和知识。其次，对不同于消耗臭氧层物质的固定相进行了评价。在这一评价中，合成了各种类型的相，并对其性能进行了测试。许多关于保留机理的新信息已经被获得。利用这些实验获得的信息，可以使用计算机能量计算和图形表示来设计新的固定相。然后通过有机化学反应合成了新相，以了解ODS法和其他固定相的实验结果。在确认了多环芳烃的选择性增强和富勒烯分离的结果后，就可以看到多环芳烃富勒烯了。这些新相是多支苯基键合相和C60键合相，都是该领域的新相。该项目已进入对新设计和合成的多环芳烃和富勒烯分离相的评估。结果清楚地表明，基本分子识别机制对这些溶质分离的选择性提高起着很好的作用。这种方法可以显示针对特定分离问题的定制固定相设计的未来趋势，该项目的价值在未来的分离科学中非常重要。

In this project, three basic approaches are introduced to propose, design, synthesize and evaluate a novel stationary phase which can offer excellent resolution and selectivity for the separations of polycyclic aromatic hydrocarbons (PAHs) and fullerenes. The steps are based on the molecular recognition mechanism. For PAHs the solutes are two dimensional molecules or steric bulky molecules. Firstly we have evaluated easily available ODS stationary phases for the separation of PAHs and fullerenes and the results provided us with the basic understanding and knowledge for designing novel stationary phases for enhancing selectivity and performance. Secondly stationary phases different from ODS phases were evaluated. In this evaluation various types of phases were synthesized and LC performance has been examined. Many new information about the retention mechanism have been obtained. With this experimentally obtained information novel stationary phases can be designed using computer energy calculations and graphical presentation. And then new phases designed were synthesized by organic reactions in order to understand the experimental results obtained by ODS and other stationary phases. After th confirmation of those results in which selectivity enhancements for PAHs and fullerenes separations are seen, one could PAHs fullerenes. Those new phases were multilegged phenyl group bonded phases and C60 bonded phases which are both new phases in this field. The project has entered into the evaluation of those newly designed and synthesized phases for PAHs and fullerenes separations. The results have clearly indicated the basic molecular recognition mechanism is working very well for the selectivity enhancements of those solutes separations. This approach can show the future trends in designing the tailored stationary phases for the particular separation problems and the value of thisproject is very important in the future separation sciences.
