Low-dimensional carbon nanostructures create a quite unique world of diverse allotropes (fullerenes, carbon dots, CNTs, graphene, nanodiamonds etc.), and their derivatives and hybrids can be prepared by approaches of both covalent and non-covalent chemistry [1]. In the present talk, the strategies towards various kinds of photoluminescent (PL) 0D-carbon dots (CDs) and 2D-graphene derivatives will be demonstrated. A quite complex issue of the PL origin in CDs will be discussed and selected applications involving tailored cell labeling, in vivo bioimaging or intracellular temperature sensing highlighted [2]. The broad and miscellaneous family of graphene derivatives will be introduced through examples of 2D-materials developed at our institute. Thus, the syntheses, properties and applications of fluorographene, thiographene, cyanographene and graphene acid will be described [3]. Specific attention will be devoted to controllable chemistry of fluorographene towards the first room-temperature non-metallic magnets, and to the development of strong organic magnets via nitrogen and sulfur doping in the graphene lattice [4]. Finally, non-covalent hybrids of graphene derivatives with CNTs, magnetic nanoparticles, MOF species or noble metal core-shell nanosystems will be discussed with respect to their use in e.g. biomedicine, separation and environmental technologies, catalysis, and ink print jet technologies [5].
