The invention relates to the use of at least one luminescent platinum complex of formula (Z) as mechanochromic, and especially piezochromic compounds, wherein said platinum complex of formula (Z) is defined by
wherein rings A, B and C are 5- or 6-members aromatic rings including atoms Xa, Xb and Xc which are linked to Platinum (Pt), wherein Xa, Xb and Xc are each independently a nitrogen atom or a carbon atom or a sulfur atom or an oxygen atom or a phosphorus atom; other members of rings A, B and C are carbon or nitrogen or sulfur or oxygen or phosphorus atoms; rings A and B are linked by a covalent bond, rings B and C are linked by a covalent bond, rings A, B and C optionally bearing one or more substituents Ra, Rb, and Rc, respectively, a is the number of substituents Ra, b is the number of substituents Rb, c is the number of substituents Rc; a, b, and c being independently 0 or from 1 to 4; Platinum ion is coordinated to a "Ligand" referred to as "L";
L is an organic ligand or an ion.
The invention also relates to such novel compounds.
