“…[2] When small amounts of aluminum hydroxide and tetramethylammonium hydroxide (TMA-OH) are added to a silica source and treated under hydrothermal conditions, high-silica zeolites such as Nu-1 [3] , Fu-1, [4] (Na, TMA)-E, [5] and sodalite [6] are formed. Furthermore, it was reported recently that the TMA ion is a template for the formation of the zeolite precursor RUB-15, [7,8] in which hemihedral cavities constitute a layered structure; however, the precise role of the TMA ions is still obscure.…”

“…[3] The incorporation of redox-active components into these molecules would serve a dual purpose, namely, to increase the host ± guest interaction with a complementary electroactive guest and to electrochemically signal the complexation event, making these molecules attractive components for sensor technology. [4] The p-electron donor tetrathiafulvalene (TTF) [5] is a good candidate as a building block for the preparation of electrochemically active macrocyclic systems with specific physical and chemical properties.…”

[3] Die Einlagerung redoxaktiver Komponenten in die Cyclophane wäre in zweierlei Hinsicht von Nutzen, da sie zum einen die Wirt-Gast-Wechselwirkung durch den Einbau eines komplementären elektroaktiven Gastes erhöhen und zum anderen den Komplexierungsvorgang elektrochemisch nachweisbar machen würde. Moleküle mit derartigen Eigenschaften wären attraktive Komponenten für die Sensortechnologie.…”
