Self‐Controlled Automated Strategy for the Synthesis of Gold Nanorods With Fine‐Tuned Longitudinal Absorption

Chemistry – A European Journal, EarlyView.
This work proposes an innovative strategy which allows to synthesize precisely tuned gold nanorods starting from nonpurified dispersions with variable aspect‐ratio. The etching process is under direct control and can be stopped at any time by oxidizer quenching, providing stable dispersions.

Twisted 1‐ and 2‐Azaperopyrenes: Synthesis, Structure, and Properties

Chemistry – A European Journal, EarlyView.
ABSTRACT A synthesis of hitherto unknown 1‐ and 2‐azaperopyrenes, twisted nitrogen‐doped peropyrenes, is reported. The synthesis is based on a Brønsted acid‐mediated benzannulation of alkynes. Key alkyne intermediates are synthesized via two complementary routes, including a Pd/C‐catalyzed, copper‐ and amine‐free Sonogashira‐type coupling of (hetero ...

Rh‐Catalyzed [2 + 2 + 2] Cycloaddition of Linked Bis(Diynes) Ar‐C≡C‐C≡C‐(CH2)3‐C≡C‐C≡C‐Ar With Quinones: Synthesis and Photophysical Properties of Bis(Arylethynyl)‐Naphthoquinones and Anthraquinones

Chemistry – A European Journal, EarlyView.
We report the synthesis bis(arylethynyl)naphtho‐ and anthraquinones via Rh(I)‐catalyzed [2 + 2 + 2] cycloaddition reactions. The substrate scope of both quinones and linked bis‐diynes was explored. Microwave irradiation remarkably enhanced yields.

Fluorescence Properties and Mg2+ Selectivity of Aryl‐Alkynyl Derivatives of the o‐Aminophenoltriacetate (APTRA) Ligand

Chemistry – A European Journal, EarlyView.
It is a challenge to improve the selectivity of high‐denticity ligands for Mg2+ over Ca2+. We show that in aryl‐alkynyl derivatives of APTRA, electron‐withdrawing substituents lower the binding affinity for Ca2+ more than Mg2+, making the ligand more selective for Mg2+.

Strong Implications From Small Deviations in Labeling Patterns: The Mechanism of Burkholderia gladioli Pacifigorgiadiene Synthase

Chemistry – A European Journal, EarlyView.
The mechanism of pacifigorgiadiene synthase from Burkholderia gladioli was investigated through isotopic labeling experiments and DFT calculations. The results revealed an unexpected labeling pattern which appeared to be different in the main and the side products, requiring unprecedented mechanistic explanations, including a “break‐flip‐cyclise ...
