Endowing Perovskite Nanocrystals with Circularly Polarized Luminescence

Advanced Materials, 2018
AbstractPerovskite nanocrystals are attracting great interest due to their excellent photonic properties. Here, through a supramolecular self‐assembly approach, the perovskite nanocrystals (NCs) with a novel circularly polarized luminescence (CPL) are successfully endowed.

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.

Circularly polarized luminescence in chiral silver nanoclusters

Chemical Communications, 2017
Sets of mirror image circular dichroism (CD) and circularly polarized luminescence (CPL) spectra are for the first time demonstrated using enantiomeric dihydrolipoic acid (DHLA)-capped silver nanoclusters.

Circularly Polarized Luminescence from Bridged Triarylamine Helicenes

Journal of the American Chemical Society, 2003
The first examples of circularly polarized luminescence from chiral bridged triarylamine-based heterohelicene molecules are reported. The luminescence dissymmetry factors are approximately |0.001|.

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 ...

Circularly Polarized Luminescence: A Review of Experimental and Theoretical Aspects

Chirality, 2016
AbstractWe review the present status of experiments and calculations for circularly polarized luminescence (CPL) of simple organic molecules and of stimuli‐responsive organic molecules. Together with the historical report of the main instrumental approaches, a few crucial points about experiments are tackled, with the aim of defining measurement ...

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 ...

Photo-Switching of Circularly Polarized Luminescence

2020
Circularly polarized luminescence (CPL) emission from chiral molecular systems is readily switched by means of external stimuli such as temperature, solvent, chemicals, and light irradiation. Since CPL is one of the emission phenomena, it can be modulated in a similar manner to the emission switching.

[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 ...
