以甲醇-水和乙腈-水为混合溶剂移动的相，研究了平面和非平面多环芳烃（PAHs）在四苯基卟啉和两种金属四苯基卟啉[Sn（IV），In（III）]键合固定相上的反相色谱行为。具有相同碳原子数但三维形状不同（例如，苯/邻三联苯和二萘嵌苯/α，α′-联萘），表明这三种四苯基卟啉基载体对小分子平面芳香族溶质具有形状选择性。平面PAH溶质在这些支持物上的容量因子显著大于具有相同碳原子数的非平面聚芳基。
The reversed-phase chromatographic behavior of planar and non-planar polycyclic aromatic hydrocarbons (PAHs) is investigated on tetraphenylporphyrin and two metallotetraphenylporphyrin [Sn(IV), In(III)] bonded stationary phases using methanol—water and acetonitrile—water as mixed solvent mobile phases. Large differences in the capacity factors of aromatic solute pairs having the same number of carbon atoms, but differing in three-dimensional shape (e.g., triphenylene/o-terphenyl and perylene/α, α′-binaphthyl), suggest that the three tetraphenylporphyrin-based supports possess shape selectivity toward small planar aromatic solutes. Capacity factors for planar PAH solutes on these supports are significantly greater than for non-planar polyaryls having the same number of carbon atoms.
