Fluorescent carbon nanomaterials, carbon nanodots (CNDs) and graphene quantum dots (GQDs), have triggered an increasing attention over the last years owing to their straightforward production methods, good photostability, biocompatibility and chemical inertness. In this contribution, we will present our efforts toward the synthesis, characterization, and modulation of properties by chemical modification of these carbon nanostructures. Special attention was dedicated to customize the optoelectronic properties of CNDs obtained by bottom-up synthesis, and the electronic communication in CND-based functional materials.1,2 Both the electron-donating and -accepting performances of CNDs make the charge-transfer chemistry of CNDs rather versatile. Charge-separated states formed by photoexcitation when CNDs have been combined with electron-donating extended tetrathiafulvalenes or electron-accepting tetracyano-anthraquinodimethane derivatives. In a different approach, the top-down synthesis of chiral GQDs by covalent or supramolecular functionalization with chiral ligands will be also presented. A chiroptical response depending on the configuration of the organic ligands introduced was observed in solution experiments.3,4 Furthermore, by means of microscopic techniques on solid surfaces, an organization at the supramolecular level was observed in some of the systems.
