During the past few decades, interest has been rapidly growing in gaining insight into the
properties and transformations of the so-called bistable compounds and molecular systems …

Photochromism is defined as a reversible transformation in a chemical species between two
forms, and in these reversible processes, at least one pathway is induced by …

We describe the preparation and characterization of photo-and mechanochromic 3D-printed
structures using a commercial fused filament fabrication printer. Three spiropyran-containing …
