Molecular configurations in LB films undergo change from keto form to zwitterion assurface pressures increase,companied by intermolecular hydrogen bonds decreaseand intramolecular hydrogen bonds increase.

在LB膜中，随表面压增加，分子间氢键减少，分子内氢键增加，SBC18头基构型在转折区发生醌式→双性离子构型转变。

When surface pressures are lower than the turnover(5～30mN/m),intermolecularhydrogen bonds were formed with keto form and phase transition was higher ca.60℃;most of SBC18 formed intramolecular hydrogen bonds companied withzwitterion form and phase transition was lower ca.48℃ while at surface pressurehigher than the turnover(≥45mN/m),which is caused by the different interchaininteraction arising from various hydrogen bonds for SBC18 LB film deposited atdifferent surface pressures.

低于相应π-A等温线转折(5～30mN/m)时，以分子间氢键为主，头基主要以醌式构型存在，相变温度较高(≈60℃)；高于转折(≥40mN/m)时，以分子内氢键为主，头基主要以双性离子构型存在，相变温度较低(≈48℃)。
