Diversity-oriented synthesis of blue emissive nitrogen heterocycles and their conjugation with carbon nano-onions

Viviana Maffeis, Lisa Moni, Daniele Di Stefano, Silvia Giordani, Renata Riva

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 1, Pages 76-89 doi: 10.1007/s11705-019-1833-0

Abstract: The search for new fluorescent molecules for possible applications as functional -electron systems and their conjugation with different nanomaterials is nowadays of paramount importance to broaden the availability of materials with different properties. Herein we present a diversity-oriented approach to heterocyclic luminophores based on a multicomponent Ugi reaction followed by a Pd-mediated cascade sequence. The new molecules are coupled to carbon nano-onions, and hybrid systems represent the first example of blue emitters conjugated with these carbon nanoparticles.
