Mechanochemical tools for polymer materials.
TL;DR: In this paper, a review of a large variety of mechanophores reported in literature is presented, and a critical evaluation of the molecular and macroscopic factors that determine their activation is provided.
From force-responsive molecules to quantifying and mapping stresses in soft materials
TL;DR: This work incorporates a spiropyran (SP) force–activated mechanophore cross-linker in multiple-network elastomers and demonstrates that the nominal stress around a loaded crack can be detected for each pixel and that the measured values match quantitatively finite element simulations.

Mechanochromism and optical remodeling of multi-network elastomers containing anthracene dimers
Huan Zhang,Dezhi Zeng,Yi-Fei Pan,Yinjun Chen,Yonghong Ruan,Yuanze Xu,Roman Boulatov,Costantino Creton,Wengui Weng +8 more
TL;DR: Multi-network elastomers with a reformable sacrificial network containing mechanochemically sensitive anthracene-dimer cross-links manifest reversible mechanochromism and remodeling.
Mechanochemistry unveils stress transfer during sacrificial bond fracture of tough multiple network elastomers.
TL;DR: In this article, multiple network elastomers containing spiropyran (SP) force sensors incorporated into the stiff filler network or into the stretchable matrix network are used to detect and investigate the mechanism of stress transfer between distinct populations of polymer strands.
Dynamic Polyamide Networks via Amide-Imide Exchange.

TL;DR: The diamide-imide equilibrium was successfully exploited for the synthesis of dynamic covalent polymer networks in which a dissociative bond exchange mechanism leads to high processibility at temperatures above ≈110 °C as mentioned in this paper.
