Winner by aggregate : Incorporating an anion‐binding squaramide group into a polymeric architecture results in drastic alterations in the selectivity and magnitude of its anion‐induced response, resulting in a sensitive and discriminating turn‐on fluorescence sensor for dihydrogenphosphate ions. This unusual behavior is the result of a cooperative, anion‐triggered aggregation process (see picture; scale bar: 1 μm).
