摘　　要：原油是最复杂的化学体系之一,人们对原油这种复杂的胶态分散体及其稳定性的研究兴趣与日俱增,尤其是与石油稳定性密切相关的沥青质超分子聚集体。但人们对形成沥青质超分子聚集体的主要作用力长期以来颇有争议。本文重点介绍了石油组分及其模型化合物在溶液中形成超分子聚集体的超分子化学作用研究进展。通过实验方法和理论计算证明沥青质聚集体是沥青质分子间通过氢键、π-π堆积、偶极-偶极相互作用等多种分子间弱相互作用力协同作用形成的热力学稳定结构;合成具有沥青质结构特点的纯化合物,研究它们在溶液中的行为,是提高对沥青质在液态相中自缔合行为认识的有效方法;结合现阶段的研究状况,对石油组分模型化合物的超分子化学作用研究的发展前景进行了展望。Petroleum is commonly described as an extremely complex mixture, the interest on the complex colloidal dispersion and its stability are growing, especially the asphaltene supramolecular aggregate which is closely related to the stability of petroleum. Meanwhile, people have been arguing about the main forces of asphaltene association. Here, the development of the supramolecular interaction in the self-associated process of petroleum components and their model compounds is reviewed. Experimental and theoretical studies have shown that asphaltenes have a strong tendency to form supramoleeular aggregates via hydrogen bonding, w-w stacking, polar interactions and other interactions. One method to improve the understanding of liquid-phase association behavior relevant to asphaltenes is to synthesize pure compounds that contain selected chemical structures, and then to examine their behavior in solution. Finally, the prospects are pointed out based on the current development of the system.
