极性基团对水具有溶剂排序效应，因此可能影响附近亲脂表面的疏水结合能。这意味着过量表面自由能缔合能的测定需要考虑附近的极性官能团。本文报告了一项衡量这种可能影响的研究结果。从此处使用的模型得出的结论是，疏水表面附近的阴离子极性基团对疏水缔合的程度影响很小或没有影响。
Polar groups have a solvent ordering effect on water and therefore may affect hydrophobic binding energies for nearby lipophilic surfaces. This would mean that determinations of excess surface free energy association energies require consideration of nearby polar functional groups. This paper reports results of a study to measure this possible effect. It was concluded from the models used here that an anionic polar group nearby a hydrophobic surface has little or no effect on the magnitude of hydrophobic association.
