Multi-color emission with orthogonal input triggers from a diarylethene pyrene-OTHO organogelator cocktail.

We report on a pyrene-decorated supramolecular gelator based on an oxotriphenylhexanoate (OTHO) that can switch emission profiles between the solution and gel phase. 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.
