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,…

Thermoresponsive Fluorescence Switches Based on Au@pNIPAM Nanoparticles

Despite numerous studies emphasizing the plasmonic impact on fluorescence, the design of a dynamic system allowing on-demand fluorescence switching in a single nanostructure remains challenging. The reversibility of fluorescence switching and the…

Design and property investigation on a five-interaction-based fluorescent anion receptor clip

A molecular clip combining a doubly substituted fluorescent anion-π donor probe and two flexible arms bearing H-bond motifs constitutes a new generation of anion receptors. Five simultaneous non-covalent interactions are highlighted by theoretical…

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…

Tetrazine molecules as efficient electronic diversion channel in 2D organic-inorganic perovskites

Taking advantage of an innovative design concept for layered halide perovskites with active chromophores acting as organic spacers, we present here the synthesis of two novel two-dimensional (2D) hybrid organic-inorganic halide perovskites…
