Structural Examination of Halogen-Bonded Co-Crystals of Tritopic Acceptors.
A series of tritopic N-heterocyclic compounds containing electrostatically and geometrically equivalent binding sites were synthesized and subjected to systematic co-crystallizations with selected perfluoroiodoarenes in order to map out their structural landscapes. More than 70% of the attempted reactions produced a co-crystal as indicated by IR spectroscopy. Four new crystal structures are rep...
متن کاملHalogen-Bonded Co-Crystals of Aromatic N-oxides: Polydentate Acceptors for Halogen and Hydrogen Bonds
Seventeen new halogen-bonded co-crystals characterized by single crystal X-ray analysis are presented from 8 × 4 combinations using methyl-substituted pyridine N-oxides and 1,ω-diiodoperfluoroalkanes. The N−O group in six of 17 co-crystals is monodentate and 11 have μ-O,O bidentate halogen bond acceptor modes. Remarkably, the N−O group in co-crystals of 3-methyl-, 4-methyland 3,4-dimethylpyridi...
متن کاملSuperfluorinated Ionic Liquid Crystals Based on Supramolecular, Halogen‐Bonded Anions
Unconventional ionic liquid crystals in which the liquid crystallinity is enabled by halogen-bonded supramolecular anions [Cn F2 n+1 -I⋅⋅⋅I⋅⋅⋅I-Cn F2 n+1 ](-) are reported. The material system is unique in many ways, demonstrating for the first time 1) ionic, halogen-bonded liquid crystals, and 2) imidazolium-based ionic liquid crystals in which the occurrence of liquid crystallinity is not dri...
متن کاملEfficient Light-Induced Phase Transitions in Halogen-Bonded Liquid Crystals
Here, we present a new family of light-responsive, fluorinated supramolecular liquid crystals (LCs) showing efficient and reversible light-induced LC-to-isotropic phase transitions. Our materials design is based on fluorinated azobenzenes, where the fluorination serves to strengthen the noncovalent interaction with bond-accepting stilbazole molecules, and increase the lifetime of the cis-form o...
متن کاملBorazine materials for organic optoelectronic applications.
Borazine materials have been demonstrated to be a new class of multifunctional and thermally stable materials with high electron (10(-3) cm2 V(-1) s(-1)) and moderate hole (10(-4) cm2 V(-1) s(-1)) mobilities for applications in electroluminescent devices.
