A chemosensor-based chiral coassembly with switchable circularly polarized luminescence

open access: yesNature Communications, 2021
‘Fluorescent chemisensors with fast response time and pronounced luminescence variation are important but have not been well investigated for self-assembled chiral systems.

Generation of Circularly Polarized Luminescence by Symmetry Breaking [PDF]

open access: yesSymmetry, 2020
Circularly polarized luminescence (CPL) has attracted significant attention in the fields of chiral photonic science and optoelectronic materials science. In a CPL-emitting system, a chiral luminophore derived from chiral molecules is usually essential.

Temperature-Dependent Circularly Polarized Luminescence Measurement Using KBr Pellet Method

open access: yesFrontiers in Chemistry, 2020
Circularly polarized luminescence (CPL) spectroscopy measures the difference in luminescence intensity between left- and right-circularly polarized light, and is often used to analyze the structure of chiral molecules in their excited state. Recently, it

Lanthanide Circularly Polarized Luminescence: Bases and Applications

open access: yesChirality, 2014
AbstractLanthanide (III) luminescence is very characteristic: it is characterized by narrow emission bands, large Stokes shift, and a long excited state lifetime. Moreover, chiral lanthanide complexes can emit strongly circularly polarized light in a way that is almost precluded to purely organic molecules.

Theoretical and experimental analysis of circularly polarized luminescence spectrophotometers for artifact-free measurements using a single CCD camera

open access: yesNature Communications, 2023
The authors present an artifact-free circularly polarized luminescence spectrophotometer using a single camera and two polarization encoding paths. The spectra are measured in a few seconds without the need of calibration by inverting the role of the ...

Circularly Polarized Luminescence in Helicene and Helicenoid Derivatives [PDF]

open access: yes, 2020
In this chapter, we discuss the circularly polarized luminescence (CPL) of helicene and helicenoid derivatives. The organic helicenic derivatives are classified according to the type of atom (heteroatom or carbon) incorporated within the helical backbone.

Manipulating the Assembly of Au Nanoclusters for Luminescence Enhancement and Circularly Polarized Luminescence

open access: yesNanomaterials, 2022
Au nanocluster (AuNCs)-based luminescent functional materials have attracted the interest of researchers owing to their small size, tractable surface modification, phosphorescence lifetime and biocompatibility. However, the poor luminescence quantum yield (QY) of AuNCs limits their practical applications. Herein, we synthesized a type of AuNCs modified

Circularly polarized lanthanide luminescence for advanced security inks [PDF]

open access: yesNature Reviews Chemistry, 2020
Authenticating products and documents with security inks is vital to global commerce, security and health. Lanthanide complexes are widely used in luminescent security inks owing to their unique and robust photophysical properties. Lanthanide complexes can also be engineered to undergo circularly polarized luminescence (CPL), which encodes chiral ...
