Gelled together : Self‐assembly and gelation studies of bis‐urea‐ and bis‐amide‐functionalised dialkoxynaphthalene chromophores (DAN‐U and DAN‐A, respectively) revealed contrasting J‐ and H‐type aggregation properties in solution, respectively (see scheme). DAN‐U was found to be a “super‐gelator” with much higher thermal stability, whereas DAN‐A showed gelation with superior mechanical stability.
