Abstract
Mechanophoric compounds featuring one or more, or two or more, clickable group(s), which are capable of being coupled to naturally occurring, synthetic and/or metallic substrates via Click chemistry, method of preparing mechanophoric matrices using the mechanophoric compounds, and mechanophoric matrices obtainable thereby, and uses thereof for detecting force-induced damage in the matrices by a colorimetric change are provided.
Claims30
A method of preparing a mechanophoric matrix, the method comprising contacting a substrate that features a plurality of a first reactive group with a mechanophoric compound that features at least one of a second reactive group, wherein said first and second reactive groups are complementary clickable groups that are capable of undergoing a click reaction with one another to thereby form a covalent Click bond therebetween, thereby preparing the mechanophoric matrix.
A mechanophoric compound represented by Formula I*:
- wherein:
- Mch is a force-responsive moiety;
- L is a linking group or absent;
- R is a clickable group which is a reactive group capable of participating in a Click reaction by forming a covalent bond with a complementary clickable group;
- and
- n is a positive integer or an integer greater than 1.
A mechanophoric matrix comprising a metallic substrate having at least one mechanophoric moiety covalently attached thereto.
