Impacts of Quinone Structure on Trade‐Offs Between Redox Potential and CO2 Binding Strength

ChemPhysChem, Volume 27, Issue 7, 14 April 2026.
Quinones are well‐studied and promising candidates for redox‐active sorbents in electrochemical CO2 capture and storage (ECCS). Unfortunately, reactivity with O2 is a persisting issue in the use of quinones. While attempts have been made to tune the redox‐potentials of quinones to avoid this, quinones which are more tolerant to the presence of O2, are ...

Chiral Heptagon‐Embedded Double [6]Helicenes via Scholl Reaction

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
One bond makes the difference–two chiral and twisted polycyclic aromatic hydrocarbons (PAHs) show different emission behavior. The more flexible one (top) shows a double emission with one having a large anti‐Stokes shift. The two peaks are assigned to different conformers of one and the same compound.

Dibenzazepin‐verbrückte Netzwerk‐Polymer‐Phthalocyanine als abbaubare heterogene Photokatalysatoren

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
Photodynamische Dibenzazepin‐Brücke wurde in Zink‐ und Kobalt‐Netzwerk‐Polymer‐Phthalocyanine (NP‐Pcs) eingeführt, um abbaubare heterogene Photokatalysatoren zu erhalten. Zum ersten Mal spielt die Bestrahlung mit Licht eine Schlüsselrolle beim „Design, der Verwendung und dem Abbau” von NP‐Pcs.

Dibenzazepine Bridged Network Polymeric Phthalocyanines as Degradable Heterogeneous Photocatalysts

Angewandte Chemie International Edition, Volume 65, Issue 16, 13 April 2026.
Dibenzazepine photodynamic bridge has been introduced to zinc and cobalt networks phthalocyanines (NP‐Pcs) to obtain degradable heterogeneous photocatalysts. For the first time, light irradiation plays a key role in “design, use and degradation” of NP‐Pcs.
