Regulation of π-stacked anthracene arrangement for fluorescence modulation of organic solid from monomer to excited oligomer emission.
The construction and precise control of the face-to-face π-stacked arrangements of anthracene fluorophores in the crystalline state led to a remarkable red shift in the fluorescence spectrum due toExpand
Rhodium(III)-Catalyzed Oxidative Coupling of N-Phenylindole-3-carboxylic Acids with Alkenes and Alkynes via C4-H and C2-H/C2'-H Bond Cleavage.
DFT calculations have suggested that the smooth insertion of an alkene to a C4-rhodated six-membered metallacycle intermediate leads to the C4 alkenylated products, while the latter annulation at the C2- and C2'-positions is attributable to facile reductive elimination in the corresponding seven- Membered meetingallacycles formed by the double C-H bond cleavage and alkyne insertion.

Guest-responsive fluorescence of inclusion crystals with π-stacked supramolecular beads.
In order to create fluorescent materials responsive to various guests, a new host supermolecule is designed that possesses two aromatic fluorophores at the periphery that efficiently incorporate and respond to a wide range of guests. Expand
Chiral recognition and kinetic resolution of aromatic amines via supramolecular chiral nanocapsules in nonpolar solvents.
An extremely high chiral recognition of 1-(1-naphthyl)ethylamine (1) in cyclohexane was achieved, with a binding selectivity of up to 41 for (S)-1 over (R)-1. Expand
Systematic investigation of molecular arrangements and solid-state fluorescence properties on salts of anthracene-2,6-disulfonic acid with aliphatic primary amines.
Systematic investigation of the organic salts of anthracene-2,6-disulfonic acid with a wide variety of primary amines constructs a library of arrangements and properties, and the library leads to remarkable strategies for the development of organic solid materials. Expand
Well-designed supramolecular clusters comprising triphenylmethylamine and various sulfonic acids.
It is described that [4+4] ion-pair clusters as an organic nanoparticle composed of triphenylmethylammonium and sulfonate ions can be obtained easily and efficiently in the solid state and in solution with many different sulfonic acid derivatives. Expand
Kinetic resolution of primary amines via enantioselective N-acylation with acyl chlorides in the presence of supramolecular cyclodextrin nanocapsules
Abstract The non-enzymatic kinetic resolution of primary amines via enantioselective N-acylation with acyl chlorides was accomplished for the first time by using the selective sequestration of oneExpand
Synthesis of Difluorinated Enynes through Sonogashira-Type Coupling.
The Sonogashira-type coupling of 2,2-difluoroethenyl tosylate with a variety of aliphatic and aromatic terminal alkynes proceeds smoothly even at room temperature to produce the correspondingExpand
Distinct Guest-Dependent Changes in Arrangements of a Fluorophore and the Corresponding Emission Modes in a Ternary System: Transcription and Translation of Guest Molecular Information
In order to prepare novel molecular arrangements of a fluorophore that result in new solid-state fluorescence properties, we fabricated a ternary system consisting of anthracene-2,6-disulfonic acidExpand
