Invited for the cover of this issue are the groups of Hans-Peter Steinrück and Peter Wasserscheid at the Friedrich-Alexander-Universität Erlangen-Nürnberg. The image depicts two Pt catalysts dissolved in an ionic liquid. For one of them, fluorinated side chains in the ligand system act as buoys leading to pronounced enrichment of the complex at the gas/IL interface, as is evidenced by strongly enhanced Pt signals in angle-resolved photoelectron spectroscopy. For the complex without fluorinated side chains, no such effect is observed. Read the full text of the article at 10.1002/chem.202203325.
本期的封面文章是由埃尔朗根-纽伦堡弗里德里希-亚历山大大学的汉斯-彼得·施泰因吕克和彼得·瓦塞尔施泰德团队提供的。图片展示了两种溶解在离子液体中的铂催化剂。对于其中一种，配体系统中的氟化侧链起到浮标的作用，导致该络合物在气体/离子液体界面处显著富集，角分辨光电子能谱中铂信号的大幅增强证明了这一点。对于没有氟化侧链的络合物，则未观察到这种效应。可在10.1002/chem.202203325阅读该文章的全文。
