“…9 Limiting the discussion to the latter kind, since their early definition by Dougherty and co-workers, [9][10][11] the importance of cation-p interactions is nowadays well established and their role is relevant to many research topics and applications, ranging from biology [12][13][14] to materials science. [15][16][17][18][19][20][21][22][23][24] In most of the aforementioned cases, however, cation-p interactions may compete with other NCIs, and the resulting biological functions or material properties are often the result of a delicate balance, settled among all contributions. 8 Very recent examples of such a complex interplay can be for instance found in the ion-driven assembly of biological catecholamines, 14 or in the competition between cation-p interactions and hydrogen bonding in mussel-inspired adhesion.…”

Organic solid‐state luminescence materials have shown great promise in many forefront areas of modern chemistry. However, the well‐developed organic luminescent solids usually provoke a mass of synthetic steps. To better utilize their performances, the development of simple strategies for host materials is a goal of general concern. Herein, a series of highly efficient solid‐state luminescence materials are attained with aid of one‐step acidification of commercially available molecules. The mechanism demonstrates that the luminous efficiency of the solid‐state molecules is efficiently improved due to the synergy from the emergence of cation–π interaction and the formation of excimer. The cation–π interaction replaces π–π packing, leading to the formation of dimers with higher rigidity in solid state accompanied by red‐shifted emissions. Therefore, this one‐step acidification design concept will light the great passion of scientists for the fabrication of cation−π‐triggered analogous organic solid‐state luminescence materials with different colors by changing the substituents on benzene moieties.

Polyoxometallate (POMs) sind molekulare Metalloxidanionen, die Anwendung in Energiewandlung und ‐speicherung, biomolekularer Chemie sowie Materialdesign und ‐integration finden. Das Wechselspiel von intrinsisch anionischen POMs mit organischen oder anorganischen Gegenionen wird häufig übersehen, ist jedoch essenziell, um die Aggregation, Stabilisierung, Löslichkeit und Funktion von POMs zu verstehen. Jenseits von einfachen Alkalimetall‐ oder Ammoniumkationen können neuartige Anwendungen durch vielseitige Kationen wie Dendrimere, mehrwertige Metallkationen, Metallkomplexe, Amphiphile oder Alkaloidkationen erzielt werden. Dieser Aufsatz gibt einen Überblick über grundlegende POM‐Kation‐Wechselwirkungen in Lösung, die daraus resultierenden Festkörperstrukturen und bespricht neuartige Reaktivitäten und Eigenschaften, die aus diesen Wechselwrkungen resultieren. Wir untersuchen, wie anwendungsnahe Forschung das Kation‐kontrollierte Design neuartiger POM‐Materialien ermöglicht hat, was wiederum den Wunsch nach der Aufklärung der Grundlagen von POM‐Kation‐Wechselwirkungen angeregt hat.
