用于高效液相色谱的四苯基卟啉基固定相是通过将卟啉的对羧基苯基衍生物通过酰胺键连接至氨丙基硅胶而制备的。这种固定相载体用于多种多环芳烃的反相分离，并且对平面芳香族溶质表现出新颖的形状选择性。随后固定的四苯基卟啉与锡(IV) 或铟(III) 发生金属化，形成具有阴离子交换特性的固定相。锡(IV) 和铟(III) 金属卟啉固定相对于芳香族磺酸盐和芳香族羧酸盐的分离都表现出有用的选择性。
A tetraphenylporphyrin-based stationary phase for high-performance liquid chromatography is prepared by attaching a p-carboxyphenyl derivative of the porphyrin to aminopropyl silica gel through an amide bond. This stationary-phase support is used for the reversed-phase separation of several polycyclic aromatic hydrocarbons and is shown to exhibit novel shape selectivity toward planar aromatic solutes. Subsequent metalation of the immobilized tetraphenylporphyrin with either tin(IV) or indium(III) results in a stationary phase with anion-exchange characteristics. Both the tin(IV) and indium(III) metalloporphyrin-based stationary phases exhibit useful selectivity for the separation of aromatic sulfonates and aromatic carboxylates.
