Hexabenzocoronene–Benzimidazole Hybrid Architectures and Faraday Rotation of the First Hexabenzocoronene–Phthalocyanine

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
The synthesis of four hexabenzocoronene (HBC) benzimidazole hybrid molecules is shown, culminating in tetra‐HBC‐Ni‐phthalocyanine (Pc). Its application as a Faraday rotator reveals a remarkable Verdet constant. The compounds are fully characterized and their optoelectronic properties investigated by electrochemistry, UV–vis, and fluorescence ...

The Diels-Alder reaction: an update

open access: yesJournal of the Brazilian Chemical Society, 2001
The last ten years have seen an explosive growth in synthetic applications of the Diels-Alder reaction, principally the intramolecular (IMDA) reaction but also the transannular (TADA) version.

Surface‐Decoupled Altitudinal and Azimuthal Triptycene‐Fused Tetrapodal Molecular Motors

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Two tetrapodal triptycene‐based light‐driven molecular motors with precisely oriented rotation axes—parallel or perpendicular to a gold surface—achieve full 360° rotation in both solution and as monolayers. The design minimizes surface quenching, enabling functional integration into surface‐mounted nanomachines.
