Journal ArticleDOI
Noncovalent ligand-to-ligand interactions alter sense of optical chirality in luminescent tris(β-diketonate) lanthanide(III) complexes containing a chiral bis(oxazolinyl) pyridine ligand.
TL;DR: Single-crystal X-ray structural analysis revealed ligand-ligand interactions between the pybox ligand and the HFA ligand in each lanthanide( III) complex: π-π stacking interactions in the Eu(III) and Tb (III) complexes with the Ph-py box ligand, CH/F interactions in those with the i-Pr-pyboxes ligand
Journal ArticleDOI
A Smart Sensing Method for Object Identification Using Circularly Polarized Luminescence from Coordination-Driven Self-Assembly
TL;DR: The potential use of circularly polarized luminescence for object identification in a sensor application is demonstrated and chemical stimuli-responsibility allow sensing using the CPL signal as detection output, enabling to discriminate between a signal from the target analyte and that from non-target species.
Journal ArticleDOI
Self‐Discriminating Termination of Chiral Supramolecular Polymerization: Tuning the Length of Nanofibers
TL;DR: A simple methodology to tune the length and optical chirality of supramolecular polymers formed from a chiral bichromophoric binaphthalene by the control of enantiomeric excess is proposed.
Journal ArticleDOI
Fingerprint signatures of lanthanide circularly polarized luminescence from proteins covalently labeled with a β-diketonate europium(III) chelate

TL;DR: Fingerprint signatures of circularly polarized luminescence (CPL) are observed from Staphylococcus aureus nuclease, bovine serum albumin, and insulin labeled with europium(III) complexes containing a β-diketonate ligand.
Journal ArticleDOI
Circular dichroism and circularly polarized luminescence triggered by self-assembly of tris(phenylisoxazolyl)benzenes possessing a perylenebisimide moiety.
Toshiaki Ikeda,Tetsuya Masuda,Takehiro Hirao,Junpei Yuasa,Hiroyuki Tsumatori,Tsuyoshi Kawai,Takeharu Haino +6 more
TL;DR: Chiral tris(phenylisoxazolyl)benzenes possessing a perylenebisimide moiety assembled to form helical stacks showed strong circular dichroism and circularly polarized luminescence, and were controlled by external stimuli.
