Photoinduced Architectural Transformation of Noncovalent Fluorescent Photochromic Organic Nanoparticles as Evidenced by Amplified Fluorescence Photoswitching

Dual nanoparticles endowed with emission photoswitching ability are produced by the flash coprecipitation of fluorophores and photochromes in water in order to investigate the mutual interplay between the self-assembled photoactive units as a…

Mechanofluorochromism of pyrenyl acrylates with different substitutional position and steric hindrance

Solid-state emission color change upon mechanical stimuli, known as mechanofluorochromism (MFC), is reported for pyrenyl acrylates. The C-1- and C-4-alkenylated pyrenes ((E)-Ethyl-3-(Pyren-1-yl)acrylate and (E)-Ethyl-3-(Pyren-4-yl)acrylate,…

A Photo- and Redox-Driven Two-Directional Terthiazole-Based Switch: a Combined Experimental and Computational Investigation

Terthiazoles with redox-active substituents like an N-methyl pyridinium group and ferrocene have been synthesized and their photo- and electro-chromic behaviors were investigated. The presence of two lateral N-methyl pyridinium substituents in the…
