Resumen: Two non-amphiphilic star-shaped 2, 4, 6-tris(1, 2, 3-triazol-4-yl)-1, 3, 5-triazines showing different behavior in terms of self-assembly and luminescent properties are described. They aggregate in the liquid phase to form low-dimensional nanostructures with a variety of morphologies, such as spherical particles, one-hole hollow spheres, toroids, twisted fibers or helical nanotubes, just by varying the conditions of a straightforward reprecipitation method. Aggregation has an opposite effect concerning the fluorescent properties of the proposed compounds, either causing the enhancement or the quenching of the emission after the self-assembly. Quantum chemical calculations have been also performed to assist in the structural and electronic characterization of the two star-shaped compounds.
