Highly Efficient Mechanochromic Thermally Activated Delayed Fluorescence in the Deep Red to Near-Infrared in Copper(I) [2.2]Isoindolinophanyl-Carbene Carbazolates. [PDF]

Angew Chem Int Ed Engl
Electrophilic [2.2]isoindolinophanyl‐based carbene iPC has been employed as charge‐transfer acceptor ligand in a series of [Cu(iPC)(carbazolate)], which show mechanochromism and environment‐dependent luminescence due to intermolecular C─‐H‐π interactions.

Revisiting Cu(I)‐Dppm Chemistry: Bright Thermally Activated Delayed Fluorescence Luminescence, Anion Dependance, Mechanochromism, and Singlet Oxygen Generation of a Dinuclear Cu(I) Homoleptic Complex

ChemistryEurope
The one‐step syntheses of highly luminescent Cu(I) dimetallic complexes are reported using Cu(I) salts and the commercially available dppm ligand. Three crystalline phases A–C, obtained either with PF6− (A and B: [Cu2(μ2‐dppm)3](PF6)2) or TEF− (C: [Cu2 ...

Programmable multimodal actuation in cholesteric liquid crystal elastomer hollow fibers beyond mechanochromism [PDF]

Nature Communications
Cholesteric liquid crystal elastomers (CLCEs) change color under strain, offering attractive prospects for soft robotics and photonic devices. However, the helical structure of CLCEs averages out the exceptional anisotropy and soft elasticity of the ...

Pyrene-Based Macrocrosslinkers with Supramolecular Mechanochromism for Elastic Deformation Sensing in Hydrogel Networks

Organic Materials, 2022
Excimer-containing polymers with supramolecular mechanochromism are an attractive and well-investigated class of mechanoresponsive materials. However, only recently steps toward mechanophore-like mechanochromic systems that are anchored within the parent

A Mechanochromic Hydrogen‐Bonded Rotaxane [PDF]

Macromolecular Rapid Communications, 2020
AbstractTensile forces influence a variety of important biological processes and force sensors are required to study these processes in vivo. Current force sensors are often tailor‐made for a specific application, or activate at much higher forces than those observed at the cellular or tissue level. A versatile force sensor, with tunable mechanical and

Preparation of Aqueous Solutions with Information on Solids Using Natural Polymers by Solid-State Mixing. [PDF]

Chem Rec
The solid‐state information, such as chiral crystal formation, crystal polymorphism, mechanochromism, room‐temperature phosphorescence, and fluorescence detection by molecular recognition, is maintained even when the functional guest molecules are solubilized in water using natural polymers.

Hypercarbon-Centered Gold(I)-Copper(I) Clusters Exhibiting a Dissolution/Crystallization-Induced Photoluminochromism. [PDF]

Chemistry
A novel photoluminochromism (PLC, > 100 nm shifts) of carbon‐centered gold cluster bearing pyridylphosphine ligands is reported. Upon dissolution/crystallization, the greenish‐yellow emissive solids and red emissive solution may reversibly convert into each other, and such processes are prohibited when utilizing pyridyl N‐heterocyclic carbene (NHC) as ...
