发现阳离子卟啉在粘土表面上的取向成功地由溶剂极性控制。用装有石英波导系统的界面光谱仪直接观察到取向的变化。在水中的粘土表面上的四阳离子卟啉是定向的，环的平面平行于硅酸盐层，而在双阳离子卟啉（顺式）的情况下，卟啉平面在添加极性较低的水混溶性溶剂时与粘土表面成直线。
The orientations of cationic porphyrins on a clay surface were found to be successfully controlled by solvent polarity. The orientational change was directly observed with the interface spectrometer equipped with a quartz waveguide system. Tetracationic porphyrins on the clay Surface in water are oriented with the plane of the rings parallel to the silicate layer, while in the case of dicationic porphyrins (cis-type), the porphyrin plane stood Lip against the clay surface on addition of less polar water-miscible solvent.
