Journal ArticleDOI
Organic chemistry: a digital fluorescent molecular photoswitch.
TL;DR: This work uses external photostimulation to switch the fluorescence on and off from a single photochromic molecule embedded in a polymer film due to photo-isomerization of the molecule, which may eventually find application in erasable optical data-storage elements.
Journal ArticleDOI
Unimolecular electrical rectification in hexadecylquinolinium tricyanoquinodimethanide

Journal ArticleDOI
Circularly Polarized Luminescence in Chiral Molecules and Supramolecular Assemblies.
TL;DR: This Perspective highlights the recent experimental and theoretical developments in the field of chiral organic chromophoric systems and their self-assembly, that has produced promising results toward the enhancement of glum values in CPL.
Journal ArticleDOI
Digital photoswitching of fluorescence based on the photochromism of diarylethene derivatives at a single-molecule level.
TL;DR: Digital on/off switching between two discrete states was observed at the single-molecule level and the "on"- and "off"-times were dependent on the power of UV and visible light.
Journal ArticleDOI
Chemical-stimuli-controllable circularly polarized luminescence from anion-responsive π-conjugated molecules.

TL;DR: This work has reported the first example of chemical-stimuli-responsive CPL properties, where appropriate pyrrole β-substituents induce distorted receptor π-planes and give larger circularly polarized luminescence (CPL), which can be tuned by chemical stimuli (anions).
