A Molecular Claw: A Dynamic Cavitand Host

Abstract

Up for grabs: A modular receptor comprises a hexaazatriphenylene "platform" and three imide residues on its concave side carrying flexible alkane chains. The chains not only populate the host's cavity but can also extend and can grab an appropriately sized and shaped guest in solution.

Theoretical prediction of the host–guest interactions between novel photoresponsive nanorings and C60: A strategy for facile encapsulation and release of fullerene

“…Moreover, the strategy for obtaining a synthetic molecule consists of employing methods of computational chemistry to design a desired host followed by experimental optimization of its synthesis. [32] So, we expect that the theoretical prediction of this work may be useful for the future experimental study and may be realized in the laboratory.…”

“…More important, this kind of host may facile release fullerene guest by the transformation of the configurations between trans‐ form and cis ‐form of the azobenzene groups upon the external stimuli of photoirradiation. Moreover, the strategy for obtaining a synthetic molecule consists of employing methods of computational chemistry to design a desired host followed by experimental optimization of its synthesis . So, we expect that the theoretical prediction of this work may be useful for the future experimental study and may be realized in the laboratory.…”

Proton‐anion Ion‐pair Recognition by a Hexaazatriphenylene‐Hexaurea Receptor

“…[17][18][19] Recently, Haley and Johnson et al demonstrated the alteration of anion binding selectivity and colorimetric response upon protonation of a series of 2,6-bis(2-anilinoethynyl)pyridine derivatives. [20][21][22] As a highly symmetric scaffold, hexaazatriphenylene (HAT) exhibits extensive applications [23] in a wide range of emerging areas including sensors, [24][25][26] self-assembled soft matter, [27][28][29][30] and optical materials. [31] However, most of the reported host-guest studies concerning HAT have generally focused on specific recognition phenomena originated from metal coordination interaction between pyridine moieties and metal ions.…”

Synthesis, Photophysical and Electrochemical Properties, and Self‐assembly Behavior of Two Hexaazatriphenylene Derivatives: A Single Bond Makes a Big Difference

“…Further light-induced oxidation coupling reaction led to thienyl-fused compound 2.T heir photophysical and electrochemical properties ands elf-assembly behavior have been investigated by UV/Vis,fluorescence, and 1 HNMR spectroscopies, cyclic voltammetry (CV), scanning electron microscopy (SEM), and powder X-ray diffraction (PXRD). Although the difference in compounds 1 and 2 only lie in one single bond that connectst he two thienyl segments, they displayed remarkably different properties, revealing an interesting structure-property relationship.In recent years, p-conjugated molecules, especially those with fused rings and containing heteroatoms such as nitrogen, boron,s ulfur or selenium, [1] have attracted attention because of their extensive applications in ar ange of emerging areas including sensors, [2] self-assembled soft matter, [3] opticalm aterials, [4] and electronic devices.[5] Among the numerousa romatic molecules, hexaazatriphenylene (HAT) has been extensivelye xplored not only as af undamentalm otif to prepare extended 2D N-substituted polycyclica romaticsb ut also as ab asic building block to fabricate av ariety of supramolecular architectures and metal complexes.[6] Due to their electron-deficient, discotic shape and rigid skeleton, HATd erivatives exhibit as trong p-p stacking tendency,w hich makes them excellent candidates for the constructiono fw ell-ordereds upramolecular architectures, [7] liquid crystals, [8] n-types emiconductors, [9] sensors, [10] nonlinearo ptical chromophores, [11] and microporous polymers.
