The construction of multiple heptagonal rings in nanographene is the key step for obtaining exotic carbon nanostructures with a negative curvature and intriguing properties. Herein, novel saddle-shaped (
Graphene nanoribbons (NRs) constitute a versatile platform for developing novel materials, where their structure governs optical, electronic, and magnetic properties while also shaping excited-state dynamics. Here, we investigate set of three twisted N-doped molecular NRs increasing length, obtained by linearly fusing perylene diimide to pyrene pyrazino- or thiadiazolo-quinoxaline residues. By employing various temperature-dependent time-resolved spectroscopy techniques, reveal how the...
Covalent functionalization of graphene oxide (GO) with boron dipyrromethenes (BODIPYs) was achieved through a facile synthesis, affording two different GO-BODIPY conjugates where the main difference lies in nature spacer and type bonds between components. The use long but flexible afforded strong electronic interactions ground state. This drastically altered light absorption BODIPY structure impeded its selective excitation. In contrast, utilisation short, rigid based on boronic esters...
Abstract Nanographenes, which feature at least one dimension smaller than 100 nm, are drawing interdisciplinary attention. Understanding the interplay between structure and properties is, however, still in its infancy. Molecular nanographenes much better suited to fill this knowledge gap graphene quantum dots or nanoribbons. Their bottom‐up synthesis allows atomic precision and, thereby, assists handling connecting it with properties. Herein, effects of nitrogen‐doping lateral π‐extension...
We report the synthesis and characterization, by means of NMR UV-visible spectroscopy electrochemical techniques, a dansyl calix[6]arene derivative its pseudorotaxane complex with bipyridinium-based axle. This novel macrocycle shows remarkable complexation ability, in analogy parent compounds, while moieties impart valuable features to system. Indeed, these units: i) signal state system fluorescence; ii) can be reversibly protonated, enabling modulation abilities macrocycle; iii) participate...
