A Simple Mechanochromic Mechanophore Based on Aminothiomaleimide
ACS Macro Letters, 2021Mechanochromic mechanophores have promising applications in stress sensing and damage detection. Here we report a simple mechanofluorochromic mechanophore based on aminothiomaleimide (ATM). Poly(methyl acrylate) containing this mechanophore (ATM-PMA) was synthesized by atom transfer radical polymerization (ATRP) using an ATM-derived difunctional ...

Reversible Mechanochromism of a Luminescent Elastomer
ACS Applied Materials & Interfaces, 2013A novel mechanochromic elastomer was manufactured by doping bis(benzoxazolyl)stibene (BBS) into a thermoplastic polyurethane. Both solution casting and melt compounding approaches were tried with a range of BBS concentrations, and an optimal concentration of 0.5% was selected to investigate the mechanochromic mechanism in detail.

A mechanochromic smart material
Polymer Bulletin, 1993A mechanochromic polyurethane elastomer was synthesized and demonstrated. Azobenzene chromophores were introduced into a copolyamide oligomer to provide conformational latches which stabilized thecis-azobenzenes by the formation of intramolecular hydrogen bonds. The copolyamide oligomer was chemically inserted into a polyurethane copolymer.

Mechanochromic Organic Micro‐Laser
Angewandte Chemie International EditionAbstractThis work presents the first demonstration of a mechanochromic organic micro‐laser, which exhibits remarkable wide range pressure sensing characteristics. The gain material, pinacolato boronate ester functionalized anthanthrene (AnBPin), is designed by incorporating mechanofluorochromic (MFC) properties into organic laser dye.

Mechanochromic polymer blends, i.e. polymer blends characterised by optical responsiveness to mechanical stimuli, have evoked major interest and experienced significant progress in recent years. Various examples are reported of chromogenic materials composed of a functional dye covalently linked to the polymer chains or physically dispersed in the ...

Solvatochromism and mechanochromism observed in a triphenylamine derivative
Acta Crystallographica Section B Structural Science, Crystal Engineering and Materials, 2019A donor–π–acceptor fluorescent dye, 4-[N,N-di(4-phenyl)amino]benzaldehyde 4-chlorobenzoyl hydrazone (TPA-CBH), based on a triphenylamine derivative (TPA) and 4-chlorobenzoyl hydrazine (CBH) was designed and synthesized. The optical properties of this luminogen were investigated in solutions as well as in the solid states.

Mechanochromic Luminescence of Fluorenyl‐Substituted Ethylenes
Chemistry – An Asian Journal, 2014AbstractIt has been reported several times that some organic luminogens with aggregation‐induced emission (AIE) characteristics exhibit the abnormal phenomenon of crystallization‐induced blueshift fluorescence, which makes them suitable for utilization as luminescence color‐switching materials.
