用红外光谱研究了一系列聚氨基甲酸乙酯-轮烷的氢键相互作用。利用光谱数据和一维平均场模型计算了聚氨酯N-H部分和位于聚氨酯主链上的大环中的醚氧原子形成氢键的焓。氢键的平均焓为3.0 kcal/mol。
The hydrogen-bonding interactions in a series of poly(urethane−rotaxane)s were studied by infrared spectroscopy. Spectroscopic data along with a one-dimensional mean-field model was used to calculate the enthalpy of hydrogen bond formation involving a polyurethane N-H moiety and an ether oxygen atom located in a macrocycle threaded along the polyurethane backbone. The average enthalpy of hydrogen bonding was estimated at 3.0 kcal/mol.
