Luminescence: Dynamic Phosphorescent Probe for Facile and Reversible Stress Sensing (Adv. Mater. 22/2017)

A dynamic phosphorescent probe incorporated into a polymer main chain can report mechanical stress with outstanding reversibility. In article number 1700563, Georgy Filonenko and Julia Khusnutdinova develop a new class of phosphorescent probe that responds to mechanical force with a rapid and reversible change in emission-lifetime characteristics while preserving its structure. This robust and fully reversible sensor has remarkable potential for assessing stress and dynamic phenomena in soft materials in a simple and accurate way.
