Mellitic Triimides:  C₃-Symmetric, Three-Electron Acceptors for Supramolecular Chemistry

Mellitic Triimides Showing Three One‐Electron Redox Reactions with Increased Redox Potential as New Electrode Materials for Li‐Ion Batteries

“…The MTIs were synthesized by a very simple two‐step procedure: the formation of the triammonium salt of mellitic acid with primary amines followed by solid‐state thermal dehydration . First, we attempted to synthesize an MTI bearing three methyl groups at the N positions as the simplest MTI molecule.…”

Entry point into new trimeric and tetrameric imide-based macrocyclic esters derived from isophthaloyl dichloride and methyl 6-aminonicotinate

“…The (EsIO) 3 dataset facilitates analysis of the molecular geometry, however, some of the bond lengths are somewhat shorter than expected due to librational motion; the orientation of the 2-pyridinyl groups are for the most part unequivocal although there is an indication of disorder in one ring (at N5), but this was not treated due to the low data:parameter ratio and negligible effect on the structure. The (EsIO) 3 molecular conformation is unusual and represents the first open-chain macrocyclic imide trimer (trezimide) to be reported, although the structurally distinct rigid triimides are known (McMenimen & Hamilton, 2001;Gawroń ski et al, 2002;Hanifi et al, 2011). Molecules of (EsIO) 3 which are (syn) 3 with respect to their isophthaloyl groups (Fig.…”

“…ester/acid/halide). Herein, when using methyl 6-aminonicotinate (as EsO), the cyclic triimide (EsIO) 3 (designated as a trezimide to distinguish it from known triimides; McMenimen & Hamilton, 2001;Gawroń ski et al, 2002) and tetraimide (EsIO) 4 (designated as a tennimide from the tennis ball seam-line) have been isolated and characterized by spectroscopic techniques and single-crystal X-ray diffraction (Scheme 1, Figs. 2 and 3).…”

Synthesis, characterization, and CO2 uptake of mellitic triimide‐based covalent organic frameworks

“…The combination of the small monomer MTA in the polymerization of A 3 with B 3 monomers contributes to the formation of porous (quasi‐) crystalline materials with hexagonal micropores (<2 nm). In addition, MTI‐based materials are being studied because of their excellent redox activity . By utilizing MTI in an A 3 –B 3 COF, we introduce a large number of active sites with respect to the overall molecular weight of the unit cell.…”

“…In addition, MTI-based materials are being studied because of their excellent redox activity. [14][15][16] By utilizing MTI in an A 3 -B 3 COF, we introduce a large number of active sites with respect to the overall molecular weight of the unit cell. Therefore, we envisage that this material could be interesting in both gas separation (due to its micropores) and energy storage (due to its redox-active groups) applications.The synthesis of MTI-COF-1 and MTI-COF-2 goes via a polycondensation reaction of MTA as trianhydride with TAPB or TAPA as primary triamines respectively, using solvothermal conditions (Scheme 1).…”
