The synthesis of novel core-substituted naphthalene diimides viaSuzuki cross-coupling and their propertiesElectronic supplementary information (ESI) available: 1H NMR and absorption spectra. See DOI: 10.1039/b9nj00476a.

This paper reports the efficient core-substitution of halogenated naphthalene diimides utilizing the Suzuki cross-coupling reaction to install various aryl substituents at the 2,6 positions. The UV-visible spectra of these compounds show a clear absorbance red shift and an enhanced fluorescence output, making them potential candidates for solar-cell dyes and electroactive elements for supramolecular materials.
