Helical Colorimetric Sensors: Stimuli‐Directed Colorimetric Interconversion of Helical Polymers Accompanied by a Tunable Self‐Assembly Process (Small 13/2019)

The image is an artistic depiction of the two structural states (helical and elongated) achieved by manipulation at the pendant groups of the poly(phenylacetylene) described in article number 1805413 by Ricardo Riguera, Félix Freire, and co‐workers, and which, after appropriate external stimuli, behaves like a colorimetric sensor that also generates controlled organogels and nanoparticles.
