Cover Feature: Supramolecular Alloys from Fluorinated Hybrid Tri⁴Di⁶ Imine Cages (Chem. Eur. J. 33/2021)

Abstract

Eight hybrid Tri4Di6 imine cages with a tuneable degree of fluorination and one fully fluorinated Tri4Di6 imine cage are formed by [4+6] dynamic imine condensation in solution. These cages with unlimited miscibility in the solid state were obtained as highly crystalline samples after recrystallization and even showed retention of the crystal lattice, forming essentially organic cage alloys mixing fluorinated and non‐fluorinated building blocks, depicted as golden honeycomb‐like structure. More information can be found in the Communication by B. M. Schmidt et al. (DOI: 10.1002/chem.202100891).

Porous Organic Compounds – Small Pores on the Rise

“…After recrystallization, these cages with unlimited miscibility in the solid‐state were obtained as highly crystalline samples that even retained the crystal lattice, forming alloys. They remained essentially nonporous although huge voids are present in the structure, because they are not interconnected, 0D pores [18] …”

“…They remained essentially nonporous although huge voids are present in the structure, because they are not interconnected, 0D pores. [18] A series of three rylene-type cages were investigated by the group of Šolomek, also extending the repertoire of POCs towards photochemistry (Figure 7). [19] The incorporated rylene diimides are not only interesting because of their strong adsorption and emission but they are also potent electron acceptors with favorable redox potentials.…”
