1,2‐Dihydroxyanthraquinone, 6,7‐Dihydroxyisobenzofuranone and 7,8‐Dihydroxyquinolinone Derivatives as Ligands for the Self‐Assembly of Hierarchically Formed Lithium‐Bridged Titanium(IV) Helicates

European Journal of Organic Chemistry, Volume 29, Issue 33, 1 September 2026.
Catechol‐based annulated aromatics with carbonyl units are ideal ligands for the formation of titanium(IV) containing lithium‐bridged hierarchical helicates. They allow for the first time the use of amide units to obtain the dimeric helicate‐type complexes.

Tunable Synthesis of Multi‐Responsive NH‐Containing Helical Nanographenes With a Chiroptical Switching Function

Angewandte Chemie, Volume 138, Issue 35, 24 August 2026.
The Scholl reaction of 1,3,6,8‐tetrakis(oligophenyl)‐appended carbazoles afforded stable NH‐containing helical nanographenes, which showed significant redshift and reversible on/off switching of CPL upon the addition of base and acid, respectively. Furthermore, excited‐state proton transfer occurred in dimethyl sulfoxide to generate anionic species ...

Hermit beetle (Osmoderma barnabita) habitat selection and movement are shaped by tree microhabitat availability in Eastern Romanian Carpathians

Insect Conservation and Diversity, Volume 19, Issue 5, Page 1015-1030, September 2026.
We conducted the first radio‐tracking study on Osmoderma barnabita to examine the movement ecology and habitat selection in the Eastern Carpathians. A female recorded the longest movement distance and had larger home ranges than males. It showed a preference for Quercus petraea, with wood mould cavities and DBH as key predictors.
