Reversible Mechanochromism of a Luminescent Elastomer

ACS Applied Materials & Interfaces, 2013
A 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, 1993
A 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 Edition
AbstractThis 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.

Solvatochromism and mechanochromism observed in a triphenylamine derivative

Acta Crystallographica Section B Structural Science, Crystal Engineering and Materials, 2019
A 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.
