The properties of graphene nanoribbons are highly dependent on structural variables such as width, length, edge structure, and heteroatom doping. Therefore, atomic precision over all these is necessary for establishing their fundamental exploring potential applications. An iterative approach presented that assembles a small carefully designed molecular building block into monodisperse N-doped with different lengths. To showcase this approach, the synthesis characterisation series constituted...

We report the synthesis and characterization of a novel type nanohoop, consisting cycloparaphenylene derivative incorporating curved heptagon-containing π-extended polycyclic aromatic hydrocarbon (PAH) unit. demonstrate that this new macrocycle behaves as supramolecular receptor π-systems such fullerenes C60 C70 , with remarkably large binding constants (ca. 107 M-1 ), estimated by fluorescence measurements. Nanosecond femtosecond spectroscopic analysis show these host-guest complexes are...

Star-shaped nanographenes (SNGs) are large monodisperse polycyclic aromatic hydrocarbons that larger than a nanometer and have shown lot of promise in wide range applications including electronics, energy conversion, sensing. Herein, we report new family giant star-shaped N-doped with diameters up to 6.5 nm. Furthermore, the high solubility this SNG neutral organic solvents at room temperature allowed complete structural, optoelectronic, electrochemical characterisation, which together...

Abstract Singlet fission has emerged as a promising strategy to avoid the loss of extra energy through thermalization in solar cells. A family dimers consisting nitrogen‐doped pyrene‐fused acenes that undergo singlet with triplet quantum yields high 125 % are presented. They provide new perspectives for nitrogenated polycyclic aromatic hydrocarbons and design materials fission.

The chemical processing of low-dimensional carbon nanostructures is crucial for their integration in future devices. Here we apply a new methodology atomically precise engineering by combining multistep solution synthesis N-doped molecular graphene nanoribbons (GNRs) with mass-selected ultra-high vacuum electrospray controlled ion beam deposition on surfaces and real-space visualisation scanning tunnelling microscopy. We demonstrate how this method yields solely controllable amount single,...

A straightforward method for the synthesis of two dibenzo[a,h]anthracene-5,6,12,13-diquinone building blocks is reported. To showcase their usefulness, a series dibenzo[a,h]anthracene nitrogenated derivatives have been synthesized that show different optoelectronic, redox, and charge transport properties, illustrating potential as organic semiconductors.

In this contribution, we focused on integrating a phenylene-bridged dibenzodiazahexacene dimer (o-DAD), which is singlet fission (SF) active, onto single-walled carbon nanotubes (SWCNTs) as low-energy sink for energetically low lying excited states that stem from SF. Spectroscopic and microscopic assays assisted in documenting SWCNT/o-DAD feature high stability THF result of electronic interactions between the individual constituents. For example, statistical Raman analysis underlined...
