Supramolecular polymorphism in dye aggregates, and examples of N,O-bidentate boron difluoride complexes are very uncommon in chemistry. Both the rarities have been addressed by synthesising a new N,O-bidentate boron difluoride...

Napthalene diimides (NDIs) are attractive candidates for electrical energy storage owing to the stabilisation of complexes between eletrogenerated dianions and cations. However, stability of such complexes are often compromised due...

Synthesis of an unsymmetrically peri-annulated naphthalene dye, perimidinium imide (PrIm) has been reported here. Compared to the symmetrical and popular analogous NDI, PrIm showed red shifted absorption maximum. The water soluble dye showed tunable self-assembly behaviors and optical properties. The dye retains its photoluminescence properties in water.
