Suzuki cross-coupling reactions were invented for the core-substitution of 2,6-dihalonaphthalene diimides with arylboronic acids. The aryl substituents at the 2,6-positions red-shift the absorbance and enhance the fluorescence of the naphthalene diimides, making them useful electroactive elements for supramolecular materials.
