TLDR
A new imidazolium-based fluorescent cyclophane 1 was designed and synthesized that was quenched selectively in the presence of iodide but not other anions, as assessed by fluorimetry.Abstract:
For your I's only: A new imidazolium-based fluorescent cyclophane 1 was designed and synthesized that was quenched selectively in the presence of iodide but not other anions, as assessed by fluorimetry. In addition, fluorescence titration experiments, 1H NMR spectroscopic data, and theoretical calculations provide evidence that 1 encapsulates two iodides inside its cavity.read more

Template Synthesis of Three-Dimensional Hexakisimidazolium Cages
Li‐Ying Sun,Narayan Sinha,Tao Yan,Yi-Shou Wang,Tristan Tsai Yuan Tan,Le Yu,Ying-Feng Han,F. Ekkehardt Hahn +7 more
TL;DR: A procedure for the synthesis of three-dimensional hexakisimidazolium cage compounds has been developed and three cyclobutane links between the two tris-NHC ligands in three [2+2] cycloaddition reactions, thereby generating a three- dimensional hexakis- NHC ligand.

Fluorescence-based sensors as an emerging tool for anion detection: mechanism, sensory materials and applications
TL;DR: A broad scope of fluorescent materials, for example, supramolecular systems, polymeric chemosensors, small molecules, metal-organic frameworks (MOFs), and aggregation-induced emissive materials, and their associated mechanisms and applications are presented in a table format as discussed by the authors.

Anion binding in aqueous media by a tetra-triazolium macrocycle.
TL;DR: Three tetra-Triazole macrocycles were synthesized in good yields by the copper(i)-catalysed cycloaddition of bis-triazole azides and bis-alkynes to give a cyclic tetracationic receptor, which complexes anions strongly in competitive DMSO-water mixtures.

Self-Consistent Equations Including Exchange and Correlation Effects
Walter Kohn,L. J. Sham +1 more
TL;DR: In this paper, the Hartree and Hartree-Fock equations are applied to a uniform electron gas, where the exchange and correlation portions of the chemical potential of the gas are used as additional effective potentials.

Inhomogeneous Electron Gas
P. C. Hohenberg,Walter Kohn +1 more
TL;DR: In this article, the ground state of an interacting electron gas in an external potential was investigated and it was proved that there exists a universal functional of the density, called F[n(mathrm{r})], independent of the potential of the electron gas.

The M06 suite of density functionals for main group thermochemistry, thermochemical kinetics, noncovalent interactions, excited states, and transition elements: two new functionals and systematic testing of four M06-class functionals and 12 other functionals
Yan Zhao,Donald G. Truhlar +1 more
TL;DR: The M06-2X meta-exchange correlation function is proposed in this paper, which is parametrized including both transition metals and nonmetals, and is a high-non-locality functional with double the amount of nonlocal exchange.
