Interfacial Enrichment and Demetallation of a Zinc Porphyrin in the Ionic Liquid [C<sub>4</sub>C<sub>1</sub>Im][PF<sub>6</sub>]. [PDF]
Upon dissolution of zinc porphyrins with long dodecyl chains in the ionic liquid [C4C1Im][PF6], partial [PF6]‐ hydrolysis occurs along spontaneous porphyrin demetallation. Driven by their buoy‐like chains, the free‐base porphyrins extremely enrich at the outermost surface as proven by angle‐resolved X‐ray photoelectron spectroscopy, an interesting ...
