Journal ArticleDOI
Concentration-dependent circularly polarized luminescence (CPL) of chiral N,N′-dipyrenyldiamines: sign-inverted CPL switching between monomer and excimer regions under retention of the monomer emission for photoluminescence
TL;DR: The reversal of the intensity ratio of monomer and excimer emission between PL and CPL was attributed to a stronger CPL (|gem| = ∼3-4 × 10-3) contribution from the minor excimer component, which should exhibit an efficient chiral environment around the dimeric pyrenes.
Journal ArticleDOI
Indolylbenzothiadiazoles with varying substituents on the indole ring: a systematic study on the self-recovering mechanochromic luminescence
Suguru Ito,Tomohiro Taguchi,Takeshi Yamada,Takashi Ubukata,Yoshitaka Yamaguchi,Masatoshi Asami +5 more
TL;DR: In this article, a series of self-recovering mechanochromic fluorophores with different solid-state emission colors and recovery times is described, based on powder X-ray diffraction and DSC analyses of crystalline and amorphous samples.
Journal ArticleDOI
Recent Advances in Mechanochromic Luminescence of Organic Crystalline Compounds
TL;DR: A growing number of MCL systems have been proposed as discussed by the authors, which refers to a reversible color change of the solid-state emission induced by mechanical stimulus such as grinding, shearing, and compressing.
Journal ArticleDOI
Efficient and versatile mechanochromic luminescence of phenanthroimidazolylbenzothiadiazoles: tricolor switching and directional control over the chromism
TL;DR: In this article, phenanthroimidazolylbenzothiadiazoles are described as a new class of highly emissive solid-state fluorophores that exhibit more versatile MCL properties.
Journal ArticleDOI
N-Boc-Indolylbenzothiadiazole Derivatives: Efficient Full-Color Solid-State Fluorescence and Self-Recovering Mechanochromic Luminescence.
TL;DR: It is proposed that the mechanism of the autonomously self-recovering mechanochromic luminescence of 3-methylindolylbenzothiadiazoles is based on a partial amorphization of the crystals upon exposure to the mechanical stimulus, followed by autonomous recovering in the form of recrystallization.
