Direct asymmetric syntheses of chiral
aldehydes and ketonesvia N-acyl chiral auxiliary derivatives including chiral Weinreb amide equivalents
This article highlights the development and applications of N-acyl derivatives of chiral auxiliaries, which are capable of functioning as latent aldehyde and ketone equivalents directly upon the cleavage of the auxiliary.
Catalytic enantioselective intramolecular cyclization of N-aryl diazoamides using a titanium–BINOLate complex
Catalytic enantioselective intramolecular cyclization of N-aryl diazoamides was achieved by using titanium–BINOLate as a chiral Lewis acid-assisted Brønsted acid.
Nucleotide sensing with a perylene-based molecular receptor via amplified fluorescence quenching
The balanced molecular state of a guanidinium-tethered perylene-based fluorescence probe was conveniently used to achieve selective sensing of UTP, and the combination of equilibrium with molecular recognition further enhances the fluorescence sensitivity.

β-Turn structure in
glycinylphenylalanine dipeptide based N-amidothioureas
Transforming the C-terminal amide of a glycinylphenylalanine dipeptide into N-amidothiourea affords a β-turn structure in the yielded dipeptide based N-amidothioureas in which the achiral phenylthiourea chromophore exhibits an induced CD signal.
Supramolecular photochirogenesis with functional amyloid superstructures
Chiral variants of amyloid fibrils prepared by chiral bifurcation of bovine insulin induced quasi-mirror-imaged CD spectra upon complexation with 2-anthracenecarboxylate and gave anti-HH-cyclodimer of the opposite absolute configurations upon irradiation.

Formation of a MPC-SH SAM resists nonspecific protein adsorption and cell adhesion on a gold electrode.
Phosphorescence from a pure organic
fluorene derivative in solution at room temperature
A fluorene derivative having both bromo and formyl groups exhibited bright phosphorescence emission in common organic solvents at room temperature.
Boron–dibenzopyrromethene-based organic dyes for application in dye-sensitized solar cells
Novel boron–dibenzopyrromethene dyes with thienyl-cyanoacrylic acid units were synthesized and characterized for application in dye-sensitized solar cells (DSSCs).
Structure–property relationships based on Hammett constants in cyclometalated iridium(III) complexes: their application to the design of a fluorine-free FIrPic-like emitter
A relationship between Hammett constants and redox potentials of cyclometalated iridium complexes is applied to match the properties of FIrPic without using fluorine.
Robust and reusable supported palladium catalysts for cross-coupling reactions in flow
Two novel polymer encapsulated silica supported palladium catalysts have been prepared and shown to be highly active, robust and recyclable catalysts for Heck and Suzuki–Miyaura cross coupling reactions under continuous flow conditions.
Two-dimensional self-assembly of amphiphilic porphyrins on a dynamically shrinking droplet surface
Unique self-assembled structures can be selectively created depending on the initial stage of the droplet. By using the droplet as a self-assembly field, we can select an appropriate self-assembly pathway by merely changing the initial state of the droplet.
The thermodynamics of the self-assembly of covalently linked oligomeric naphthalenediimides into helical organic nanotubes
The mechanism and thermodynamic functions of the self-assembly of a family of covalently linked oligomeric naphthalenediimides (NDIs) were investigated through variable-temperature NMR and CD studies.
Acylthioureas as anion transporters: the effect of intramolecular hydrogen bonding
The effects of intramolecular hydrogen bonding on the efficiency of anion transport are explored in a series of acylthioureas.
Triggered formation of thixotropic hydrogels by balancing competitive supramolecular synthons
Two component thixotropic co-gels arise from rapid precipitation leading to fibre assembly.
Recognition between V- and dumbbell-shaped molecules
Diimine-based V-shaped compounds which have been investigated for binding with dumbbell-shaped ammonium cations, have been characterised by NMR and fluorescent spectroscopies.
An approach to 8 stereoisomers of homonojirimycin from
D-glucosevia kinetic & thermodynamic azido-γ-lactones
A sweet combination of synthesis and biotechnology paves the way from D-glucose towards eight of the 16 stereoisomers of homonojirimycin.
