“…In the past few years, they were extensively studied in applications spanning photonics and optoelectronics, advanced electrodes, nanomedicine, etc. [84][85][86][87][88]. In recent years, CNFs emerged as suitable support for heterogeneous catalytic materials, due to their high chemical inertness, thermal stability, and mechanical resistance, along with an unconventional lightness [89].…”

The conversion of carbon dioxide into valuable chemicals such as cyclic carbonates is an appealing topic for the scientific community due to the possibility of valorizing waste into an inexpensive, available, nontoxic, and renewable carbon feedstock. In this regard, last-generation heterogeneous catalysts are of great interest owing to their high catalytic activity, robustness, and easy recovery and recycling. In the present review, recent advances on CO 2 cycloaddition to epoxide mediated by hybrid catalysts through organometallic or organo-catalytic species supported onto silica-, nanocarbon-, and metal-organic framework (MOF)-based heterogeneous materials, are highlighted and discussed.

“…Three reversible oxidation waves were observed at 0.09, 0.40 and 0.65 V versus a ferrocene/ferrocenium couple ( Figure 6). The parent structures, t-BuHBC and alkynyl- [6]helicene M-(À)-2 were also measured under the same experimental conditions (see supporting information, Figures S7,S8). t-BuHBC showed one reversible oxidation wave at 0.74 V and the helicene showed no oxidation within the solvent window.…”

“…[2] Recently, the first examples of graphene quantum dots with chiroptical properties have also been reported. [3,4] These nanographenes have been the subject of an explosion of research in recent years, showing promise the fields of photovoltaics, [5,6] and sensing. [7] The simplest member of the synthetic nanographene class is hexa-peri-hexabenzocoronene (HBC) which itself has been the subject of much research.…”

“…assembled the two HBC layers and extended the helicene backbone from [6]-to [10]helicene, yielding the desired HBNG, 5 with a good overall yield (33 % for the racemate, 16 % for the M-isomer). For M-5, circular dichroism spectroscopy confirmed the retention of configuration after each step ( Figure 5 and Supporting Information, Figures S4,S5) and the overall enantiomeric excess was determined by chiral HPLC of 5 to be 93 %.…”

A rigid, inherently chiral bilayer nanographene has been synthesized as both the racemate and enantioenriched M isomer (with 93 % ee) in three steps from established helicenes. This folded nanographene is composed of two hexa‐peri‐hexabenzocoronene layers fused to a [10]helicene, with an interlayer distance of 3.6 Å as determined by X‐ray crystallography. The rigidity of the helicene linker forces the layers to adopt a nearly aligned AA‐stacked conformation, rarely observed in few‐layer graphene. By combining the advantages of nanographenes and helicenes, we have constructed a bilayer system of 30 fused benzene rings that is also chiral, rigid, and remains soluble in common organic solvents. We present this as a molecular model system of bilayer graphene, with properties of interest in a variety of potential applications.
