Multi-Color Emission with Orthogonal Input Triggers from a Diarylethene Pyrene-OTHO Organogelator Cocktail

Abstract

<div><div><div><p>Controlling spectral and physicochemical properties with external stimuli is vital for the development of smart materials. Here we demonstrate a supramolecular gelator based on a fluorescent oxotriphenylhexanoate (OTHO) that can switch emission profiles between the solution and gel phase. Furthermore, a cocktail of the gelator and a photochromic diarylethene derivative enables four distinct emissive states to be obtained, which are modulated with light and heat as orthogonal input triggers.</p></div></div></div>
