Abstract

Abstract : A new class of rationally designed mechanophores is developed for highly sensitive built‐in strain sensors in polymer composites. These mechanophores are designed to regenerate the π‐conjugation pathway between the electron donor and electron acceptor by force‐induced cleavage of the covalent bond to form a fluorescent dipolar dye.
