在甲苯/水体系的界面上，H4 TPyP 4+和CuTPPS 4-形成了异相聚集体，能够识别D-和L-苯丙氨酸（Phe）等氨基酸的手性，但H4 TPyP 4+和CuTPPS 4-均不能识别氨基酸的手性。聚集体中H4 TPyP 4+：CuTPPS 4-的组成估计为1：1，如在水溶液中报道的。但是，界面异质聚集体的CD光谱与水溶液中的不同，表明不同的手性相互作用。本研究结果表明，一种新的模式的界面手性反应所表现出的协同效应的异相聚集的带负电的卟啉。
At the interface of the toluene/water system, H4TPyP4+ and CuTPPS4- formed heteroaggregates, which could recognize the chirality of D- and L-phenylalanines (Phe) and other amino acids, though neither H4TPyP4+ nor CuTPPS4- could indicate the chirality of the amino acids. The composition of H4TPyP4+:CuTPPS4- in the aggregate was estimated as 1:1 as reported in an aqueous solution. But, CD spectra of the interfacial heteroaggregates were different from that in the aqueous solution, suggesting different chiral interaction. The present results suggest a new mode of the interfacial chiral reaction exhibited by the synergistic effect of the heteroaggregation of the inversely charged porphyrins.
