Through integrated experimental and theoretical approaches including electrostatic potential (ESP) analysis, molecular binding energy calculations, Atoms in Molecules (AIM) theory, and spectroscopic characterization, we reveal how structural variations (carbon chain length, unsaturation degree, spatial configuration, and functional groups) modulate hydrogen bond characteristics. Results show that extending carbon chains enhances hydrogen bond strength (TBPO-18: -24.28 kcal/mol binding energy), while increasing unsaturation initially weakens then strengthens interactions. Linear structures exhibit superior hydrogen bonding versus cyclic configurations (TBPO-OH vs TBPO-HOH: 18.60 vs 14.47 kcal/mol). Extraction performance correlates with hydrogen bond stability, where TBPO-12 achieves maximum capacity (40.55 mg/L) due to optimal acid resistance.
