摘要：

For the first time molecular images of liquid-phase-adsorbed aromatics on a zeolite surface were obtained. Pyridine molecules adsorbed on a cleaved stilbite(010) surface from an aqueous solution were imaged by contact-mode atomic force microscopy. Adsorbed pyridine appears to form a 2-dimensional quasi-solid phase on the surface. The adsorbed layer exhibits an approximately hexagonal symmetry, with a unit cell dimension of 5.1 +/- 0.3 Angstrom. Molecular orientation within the adsorbed layer is also discussed.
