“…To overcome this tendency to aggregate, functionalization of the surface of the carbon materials is the method of choice. The covalent as well as the non-covalent functionalization of CNTs [ 22 – 24 ] have been widely studied in the past decades and can serve as inspiration for possible synthetic strategies to decorate CNOs with a variety of functional groups and also to increase the solubility of CNO materials.…”

SummaryThis review focuses on the development of multi-layer fullerenes, known as carbon nano-onions (CNOs). First, it briefly summarizes the most important synthetic pathways for their preparation and their properties and it gives the reader an update over new developments in the recent years. This is followed by a discussion of the published synthetic procedures for CNO functionalization, which are of major importance when elucidating future applications and addressing drawbacks for possible applications, such as poor solubility in common solvents. Finally, it gives an overview over the fields of application, in which CNO materials were successfully implemented.

“…Synthetic procedures for the covalent functionalization of CNOs are largely based on previously described strategies for the functionalization of CNTs [ 22 , 24 ]. The first study reporting covalently functionalized CNOs was published in 2003, in which Prato et al described an azomethine ylide addition reaction on CNOs [ 25 ] ( Scheme 2 ).…”

“…Zuerst werden wir die wichtigsten Konzepte in Bezug auf die nicht‐kovalente und kovalente Funktionalisierung von MoS 2 und BP diskutieren und evaluieren. Unsere eigene Arbeitsgruppe hat zu dieser Entwicklung in der genannten chronologischen Abfolge ebenfalls beigetragen, ausgehend von der Chemie des Graphens (die wiederum auf unserer Erfahrung mit der Fulleren‐ und Kohlenstoffnanoröhrenchemie beruht) über die Funktionalisierung von MoS 2 und BP …”

Der aktuelle Wissensstand über die chemische Funktionalisierung dreier 2D‐Materialien – Graphen, Molybdändisulfid und schwarzer Phosphor – wird zusammengefasst. Diese 2D‐Polymere repräsentieren derzeit ein aufstrebendes Forschungsgebiet an der Schnittstelle zwischen Synthesechemie, Physik und Materialwissenschaften. Die kovalente und die nicht‐kovalente Funktionalisierung von Schichtstrukturen ermöglichen eine systematische Modifizierung ihrer Eigenschaften, z. B. die Verbesserung der Löslichkeit und Prozessierbarkeit, die Vermeidung von Reaggregation oder eine Änderung der Bandlücke. Außer erfolgreichen Funktionalisierungskonzepten werden auch grundlegende Schwierigkeiten angesprochen. Dazu zählen die Unlöslichkeit und Polydispersität der meisten 2D‐Schichtsysteme, die Identifizierung effektiver Strategien zur Bildung einer chemischen Bindung und die Regioselektivität von Additionsreaktionen in einer Basalebene. Im vorliegenden Aufsatz werden die wichtigsten und vielversprechendsten Konzepte zur Bewältigung dieser Probleme vorgestellt.

The current state of the chemical functionalization of three types of single sheet 2D materials, namely, graphene, molybdenum disulfide (MoS2), and black phosphorus (BP) is summarized. Such 2D sheet polymers are currently an emerging field at the interface of synthetic chemistry, physics, and materials science. Both covalent and non‐covalent functionalization of sheet architectures allows a systematic modification of their properties, that is, an improvement of solubility and processability, the prevention of re‐aggregation, or band‐gap tuning. Next to successful functionalization concepts, fundamental challenges are also addressed. These include the insolubility and polydispersity of most 2D sheet polymers, the development of suitable characterization tools, the identification of effective binding strategies, the chemical activation of the usually rather unreactive basal planes for covalent addend binding, and the regioselectivity of plane addition reactions. Although a number of these questions remain elusive in this Review, the first promising concepts to overcome such hurdles are presented.
