Consequently we found two principal results in this investigation.(1) The crystal structures of molecular crystals formed from different chlorobenzoic acids and three kinds of organic bases showed that in addition to common hydrogen bondings, the weaker intermolecular interactions such as the C-H…O hydrogen bonding, the π-π stacking and electrostatic interaction play an important role in determining the packing modes of each molecular crystal.

在对双分子晶体结构的研究过程中，我们发现存在以下两条规律：（1）不同的氯苯甲酸与三种有机碱形成的双分子晶体的结构显示，除了常见的氢键作用外，弱的分子间相互作用，例如C-H…O类型的氢键、π—π相互作用、静电相互作用等对于不同分子堆积模式的形成也起到了很重要的作用。

Hydrogen bondings induced from carboxylic groups were intentionally designed at the end of the arm of these star-shaped molecules. The hydrogen bonding positions of the so-perpared star-shaped oligofluorenes were similar to those of trimestic acids which has been intensively studied, and this enlightened us to design these moleucles.

In this thesis, two chemical structural models were constructed based on several structure parameters derived from FTIR and 13C NMR data, which were processed by curve-fitting and curve-resolved. Modified models were obtained by simulation oftheir molecular vibration spectra using Cerius 4.6/IR module andthe structural parameters from 13C NMR. Potential energy, bondenergy and non-bond energy of the minimum-energy conformations of coal macromolecules were calculated by molecular mechanics calculation and molecular dynamics simulation. These results demonstrate the importance of hydrogen bonding and van der Waals interactions in the formation and stabilization of coal macromolecular structure, and a strongest tendency of hydrogen bonding interactions to increase with the coal molecules but the Coulombs force.
