Photochromic Diarylethenes with a Curved Aromatic Corannulene Unit. [PDF]

open access: yesACS Omega
We report new photochromic diarylethenes incorporating a curved aromatic corannulene unit as a side aryl group: 1-(2-methoxycorannulenyl)-2-(2-methyl-5-phenyl-3-thienyl)perfluorocyclopentene (1) and its sulfone derivative, 1-(2-methoxycorannulenyl)-2-(1,1-dioxide-2-methyl-5-phenyl-3-thienyl)perfluorocyclopentene (2).

Distinct Nanohoop Structures and Ratiometric Emissions of Isomeric DPAC‐Based Macrocycles Tuned by Nano‐Twisting of Stiff‐Stilbene Optical‐Switches

open access: yesSmall, EarlyView.
Tunable nano‐twisted structures of novel isomeric macrocycles, which were controlled by cis/trans isomerizations of stiff‐stilbene units under light irradiations, have been exploited to modulate bent and planar configurations of 9,14‐diphenyl‐9,14‐dihydrodibenzo[a,c]phenazine (DPAC) moieties and adjust their ratiometric emissions. External factors, i.e.

Improving the Fatigue Resistance of Diarylethene Switches

open access: yesJournal of the American Chemical Society, 2015
When applying photochromic switches as functional units in light-responsive materials or devices, an often disregarded yet crucial property is their resistance to fatigue during photoisomerization. In the large family of diarylethene photoswitches, formation of an annulated isomer as a byproduct of the photochromic reaction turns out to prevent the ...

White light emitting molecular logic gates

open access: yesSmart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.
