Temperature-Dependent Circularly Polarized Luminescence Measurement Using KBr Pellet Method

Frontiers 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

Circularly Polarized Luminescence in Helicene and Helicenoid Derivatives [PDF]

, 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.

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

Nature 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 ...

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

Nanomaterials, 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]

Nature 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 ...

Force-Induced Control of Circularly Polarized Luminescence With Rotaxane Architecture. [PDF]

Angew Chem Int Ed Engl
Force‐induced reversible on/off switching of circularly polarized luminescence is achieved with a rotaxane‐based supramolecular mechanophore. The mechanophore, featuring a chiral helicene luminophore, is incorporated as a first network cross‐linker into a double‐network organogel.
