Cadmium- and zinc-directed assembly of nano-sized, resorcarene-based host architectures which strongly bind C60

Abstract: Nano-sized molecular loops based on a trimer of resorcarene ligands assembled by six cadmium or zinc ions are shown to strongly bind the spherically shaped fullerene C 60 in toluene and benzene solutions.

“…[2] Nowadays, fullerene derivatives are the benchmark n-type materials for the construction of organic photovoltaic devices. [3,4] The search for molecular receptors for fullerenes was initiated just seven years after the discovery of C 60 and immediately after it became available in sufficient quantities by contact-arc vaporization of graphite. [5] From the point of view of molecular recognition, fullerenes are very peculiar guest molecules.…”

“…In addition to methyl ammonium derivatives, resorcarenes also bind several other guests; the forces that affect the complex formation of resorcarenes are purely noncovalent, such as hydrogen bonding, cation-and CH-interactions [9]. Large resorcarene-based assemblies even bind fullerenes [10]. Overviews have been published on resorcarenes in general and on their host-guest chemistry [1,11].…”

“…In diesem Sinne wäre wohl die Reduktion des Butadiin-Linkers auf sein Alkylanalogon interessant gewesen, wie es später für makrocyclische Porphyrin-Dimere beschrieben wurde. [14] Im Fall von Wang und Gutsche [13] waren die Ergebnisse sogar noch schlechter, da ihre [4]-und Calix- [6]aren-Käfige keinerlei Affinität für C 60 [20] Die Herstellung der Derivate 10 a und 10 b (Abbildung 4) ist erstaunlich einfach, und beide werden ausgehend von 1,3-Diaminobenzol und 2,6-Dibrompyridin in drei Schritten gewonnen. [21] Im Gegensatz zu 10 b führt die Zugabe von 10 a zu einer C 60 Toluol bei 298 K, wobei sie allerdings den Effekt einer mçg-lichen dynamischen Fluoreszenzlçschung vernachlässigen.…”

“…[27b] Ausgehend von einer Mischung von 14 und C 60 CN (95:5). [28] In Anbetracht der Tatsache, dass weder Calix [4]pyrrol noch Pyren alleine in der Lage sind, mit Fullerenen stabile Komplexe zu bilden, bestätigt das Beispiel 15 zweifellos, dass die Pyrrolringe zur Erkennung von Fullerenen beitragen.…”
