【Abstract】 On the basis of coal molecular component and noncovalent interaction in coal, the concept of coal supramolecular structure, which is formed by noncovalent interaction and molecular recognition, was proposed.The research contents, approach and methodology were discussed.The research contents include:① coal molecular components and their structure; ② the interaction among coal molecules; ③ coal molecular recognition; ④ characterization of coal supramolecular molecular and physical chemical mechanism for its formation.The research approach and methodology are the combination of experimental and modeling.Based on experimental results, the characteristics and formation process of coal will be revealed by molecular simulation, which can be used to understand the synergism effect of force among molecules and configuration and conformation of coal molecules on formation of coal supramolecular structure.更多还原
