Unraveling Ultrasonic Stress Response of Nanovesicles by the Mechanochromism of Self-Assembled Polydiacetylene [PDF]

The force response of nanosized vesicles shows substantial applications in drug delivery, cancer therapies, and so on. Conventional methods in mechanical studies on vesicles rely on a camera and an optical microscope, which can hardly work for nanosized ...

Preparation of Polymerizable Mechanochromic Gelator

Crystals
Mechanochromism is a phenomenon in which mechanical stimuli change the optical properties of a material, such as its color and emission properties. Various materials exhibiting this behavior have been intensively studied.

Mechanochromic Polyolefin Elastomers

ACS Applied Polymer Materials
The optical detection of mechanical strain and stress in polymers is a powerful and convenient approach for studying deformation processes in these materials and identifying damage prior to failure in crucial components. We show here that mechanochromic behavior can be introduced via a straightforward one-step process that involves the modification of ...

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

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 ...

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 ...
