The torsion angle around the sulfonamide bond gives these oxyanion hole-like receptors a variable size cleft. As stronger H-bonds imply shorter distances between H-bond donors and acceptors, these clefts with sulfonamide and carboxamide functions might be of interest in catalysis. X-ray crystal structures confirm the formation of two strong linear H-bonds between the NHs and carbonyl or alcohol oxygens, showing the adaptability of the cleft.

基于 8-Sulfonamide-2-Naphthoic 酸的可调节裂缝，具有氧阴离子孔几何结构

磺酰胺键周围的扭转角使这些氧阴离子孔状受体具有不同大小的裂缝。由于更强的氢键意味着氢键供体和受体之间的距离更短，这些具有磺酰胺和羧酰胺功能的裂缝可能对催化感兴趣。X 射线晶体结构证实在 NH 和羰基或醇氧之间形成了两个强线性 H 键，显示了裂缝的适应性。
