4,4‐Difluoro‐4‐bora‐3a,4a‐diaza‐s‐indacene (BODIPY) derivatives bearing varied substituents at the meso position (i.e., CF3, CH3, COOR, CHO, CN, Cl, iPr) were synthesized to elucidate the structure–property relationships that give rise to emissive J‐aggregates. Several new BODIPY derivatives can be added to the previously reported 1,3,5,7‐tetramethyl‐8‐trifluoromethyl derivative to the list of those

rapid colorimetric and fluorescent indicator 1 has been developed for the qualitative and quantitative determination of water. The water-induced sensitive (LOD = 0.003%, v/v) and fast (<10 s) change in emission properties was applied to the determination of water in organic solvents, drugs, and foodstuffs in both solution and practical solid-state indicator paper strips.
