Abstract
Polydiacetylene is a mechanochromic polymer that changes its color and emits fluorescence when it is stimulated by force, heat, pH change etc., used in a variety of sensing applications. However, the fundamental mechanism of its mechanochromism at the nanoscale is still not completely understood because of a lack of technique. Recently, our lab has introduced the dual friction force/fluorescence microscopy setup to characterize polydiacetylene. In this mini–review, we will present our recent results, where polydiacetylene is characterized by this technique.
