Bernet, A.; Albuquerque, R.Q.; Behr, M.; Hoffmann, S.; Schmidt, H.-W.: Formation of a supramolecular chromophore: a spectroscopic and theoretical study, Soft Matter 8(1), 66-69 (2012) -- DOI: 10.1039/c1sm06789c
Spectroscopic and theoretical investigations of the self-assembly of a particular 1,3,5-benzene trisamide-based low molecular weight hydrogelator are described. This trisamide is pH-sensitive, and surprisingly forms a photoluminescent supramolecular hydrogel. Controlled gel formation in combination with the luminescence properties allows studying the self-assembly process in detail. The experimental results are confirmed by Density Functional Theory (DFT) calculations, revealing that the photoluminescence originates from the formation of a supramolecular chromophore.
