ATP‐Induced Emergent Circularly Polarized Luminescence and Encryption

Angewandte Chemie, 2022
AbstractBiomimetic ATP‐driven supramolecular assembly is important to understand various biological processes and dissipative systems. Here, we report an ATP‐driven chiral assembly exhibiting circularly polarized luminescence (CPL) via the interaction of an achiral terpyridine‐based ZnII complex with nucleotides.

Chirality Induction on a Coordination Capsule for Circularly Polarized Luminescence

Angewandte Chemie International Edition, 2022
AbstractBy utilizing a confined space inside a coordination capsule consisting of achiral components, we achieve trimeric structures composed of acetic acid and 2,3‐disubstituted tartaric acid derivatives. Steric and electronic interactions between the substituents on the tartaric acid and 2,2′‐bipyridyl arms of the capsule permit the transfer of the ...

Magneto‐Luminescence Thermometry with Magnetic Circularly Polarized Luminescence

Angewandte Chemie International Edition
Abstract Lanthanide(III) materials display remarkable optical properties, making them valuable for advancing remote luminescent sensors. The narrow emission bands and energy‐transfer processes can be tailored to respond to external stimuli, such as temperature changes and magnetic fields.

Enhancement of Circularly Polarized Luminescence from Pulsating Nanotubules

Macromolecular Rapid Communications, 2023
AbstractEnhancing the dissymmetry factor (glum) is a crucial issue in developing circularly polarized luminescence (CPL) materials. Herein, based on supramolecular self‐assembly of diethyl l‐glutamate‐cyanodiarylethene (L‐GC) in mixed solution of EtOH‐H2O with different water fraction, enhanced circularly polarized emission from pulsating nanotubules ...

Circularly Polarized Luminescence Switching in Small Organic Molecules

Chemistry - A European Journal, 2019
AbstractThe circularly polarized luminescence (CPL) switching is of significant interest for applications in security technologies and sensing devices. Small organic molecules (SOMs) show several advantages over metal complexes, supramolecular assemblies, and polymers. Therefore, the recent progress on the CPL switching in SOMs is here reviewed.

[7] Circularly polarized luminescence

1978
Publisher Summary This chapter focuses on circularly polarized luminescence. It investigates specifically how it is measured and what it may reveal about the molecules producing it. The occurrence of circularly polarized light in the luminescence of chiral molecules can be rationalized in terms of the known correspondence between absorption and ...
