Bay‐functionalized [7]Helicene Bilayer Nanographenes
Advanced Optical Materials, Volume 14, Issue 13, 3 April 2026.Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

Advanced Synthesis &Catalysis, Volume 368, Issue 7, 1 April 2026.A dioxolanyl linchpin has been used to synthesize aryl ethanolamines from readily available aryl bromide and amine starting materials using a metallaphotoredox/substitution telescoped sequence. This combinatorial approach allows for a wide synthetic scope of both heteroarenes and cyclic amines. Aryl ethanolamines are an important functional group found

, 2023 Quinoxalines are a group of antibiotics widely used in medicine to fight bacterial infections.These antibiotics have a broad spectrum of action and belong to the class of 4 quinolones. Theirmechanism of action is based on inhibiting the activity of bacterial enzymes responsible for DNAsynthesis, which leads to their death. Due to this, quinoxalines are
