Iterative Synthesis of Pyrene–Coronene Molecular Graphene Nanoribbons

open access: yesAngewandte Chemie, EarlyView.
An iterative approach delivers a new family of undoped, cove‐edged graphene nanoribbons with lengths up to 9.1 nm that exhibit both molar absorptivity and fluorescence brightness values on the order of 105 M−1 cm−1 and an intrinsic charge‐carrier mobility of 475 ± 32 cm2 V−1 s−1.

Auf dem Weg zu chromoselektiven Transformationen in biologischen Systemen: Perspektiven und Herausforderungen

open access: yesAngewandte Chemie, EarlyView.
Die Kontrolle biologischer Systeme mit organischen Chromophoren hat sich zu einer vielversprechenden Strategie entwickelt und findet Anwendung von der chemischen Biologie bis hin zur Medizin. Die Komplexität von In‐vivo‐Systemen lässt sich jedoch nicht mit nur einer einzigen Lichtwellenlänge adäquat abbilden.

Syntheses of Pyrene-4,5-dione and Pyrene-4,5,9,10-tetraone

open access: yesThe Journal of Organic Chemistry
Improved gram scale synthesis procedures for the preparation of pyrene-4,5-dione and pyrene-4,5,9,10-tetraone are reported. Pyrene-4,5-dione has been synthesized using potassium persulfate as the oxidant and RuO2·nH2O as the catalyst in the biphasic CH2Cl2/H2O solvent mixture containing K2CO3 as the base.
