Mechanochromic Luminescent Materials

Mecanochromic luminescent materials are smart materials which change their emission colors when a mechanical force such as grinding is applied, while they can recover their initial emission by fuming or heating processes.

A class of mecanochromic luminescent materials are metal complexes. Most of such complexes are based on expensive metals such Pt(II), Ir(III) or Au(I).

This technology offer presents a new type of complex based on cheaper metals such bismuth or lead. These mecanochromic luminescent materials are coordination polymers based on simple ditopic ligand such
N-oxide-4,4’-bipyridine.

KEY BENEFITS:
• Cheap metals and ligands
• High quantum yield
• Wavelengths range :
-un-grinded material : between 450 and 600 nm
-grinded material : between 500 and 650 nm
