摘要: 运用分子动力学(MD)模拟方法对杯[4]吡咯与不同溶剂之间的相互作用能、杯[4]吡咯在不同溶液中的构象变化以及杯[4]吡咯与溶剂分子之间的氢键相互作用进行了计算研究.模拟发现,杯[4]吡咯与不同溶剂间的相互作用能受溶剂分子偶极矩和杯[4]吡咯-溶剂分子间氢键相互作用影响.杯[4]吡咯在不同溶液中的构象发生翻转的主导因素是杯[4]吡咯与溶剂分子间形成氢键相互作用,溶剂分子的偶极矩不是杯[4]吡咯发生构象转化的主要因素.

Abstract: The interaction between calix[4]pyrrole and different solvents, conformational interconversion of calix[4]pyrrole in different solutions and hydrogen bond interaction between calix[4]pyrrole and solvent molecules were investigated by a series of MD simulation. The interaction between calix[4]pyrrole and solvents is affected by the dipole moment of solvent molecules and the hydrogen bond interaction between calix[4]pyrrole and solvents. The formation of hydrogen bond between calix[4]pyrrole and solvents is the main factor for conformational intercoversion, and the dipole moment of solvent molecule is not important in the conformational intercoversion.
