Design, Synthesis, and Photophysical Studies of Functionalized Polyaromatic Isonitriles as Visible Light Photoredox Catalysts

European Journal of Organic Chemistry, Volume 29, Issue 25, 4 July 2026.
A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.

Evaluation of Photophysical Properties and Biological Applications of Diarylmethanes

ChemistryOpen, Volume 15, Issue 6, June 2026.
The wide applications of diarylmethanes were investigated through various experimental and computational approaches. The solvent environment influences the electronic properties of diarylmethanes and hence their drug‐like properties. Interactions with PARP1 revealed stable binding supporting anticancer potential.

Expeditious Synthesis of Phenanthridines from Benzylamines via Dual Palladium Catalysis

, 2010
A method for the synthesis of phenanthridines from benzylamines and aryl iodides which uses a dual palladium-catalyzed process is developed. The domino sequence ends via an intramolecular amination and an oxidative dehydrogenation. No protecting group or

Selective Fluorescent Probe Based on Thiomethyl‐Substituted Bis(arylidene)ketone for Hypochlorite Detection in Water Samples

ChemistrySelect, Volume 11, Issue 21, 4 June 2026.
The synthesized probe (SMAK) is the first bis(arylidene)ketone derivative for hypochlorite sensing. It was prepared in one step following two alternative routes; the traditional solution method and a greener solvent‐free method. Probe was found to have excellent selectivity over interfering anions, cations and oxidants and the mechanism of sensing and ...

Synthesis and Characterization of Carbazole‐Containing Aza[7]helicenes

Chemistry – A European Journal, Volume 32, Issue 19, 22 May 2026.
Double ortho fusion led to different aza[7]helicene frameworks showing strong acidochromic behavior, singlet excited energies being more than twice the triplet energy, and high racemization barriers, allowing chiral resolution and ECD measurements. ABSTRACT Azahelicenes have attracted significant interest due to their intrinsic axial chirality and ...

Mo‐Catalyzed Synthesis of N‐Polyheterocycles From Functionalized Nitroarenes and Aldehydes

Asian Journal of Organic Chemistry, Volume 15, Issue 5, May 2026.
Mo(VI)‐catalyzed one‐pot conversion of readily available functionalized nitroarenes and aldehydes yielded fused N‐polyheterocycles by sequential nitro reduction, imine formation, and cyclization. Using pinacol as a benign reductant, this sustainable tandem strategy suppresses side reactions and grants rapid access to diverse pharmacologically relevant ...

Uracil–Peptide–Pyrene Conjugates as Cu2+‐Sensitive Probes Targeting DNA, RNA, and Biorelevant Model Membranes

ChemBioChem, Volume 27, Issue 8, April 2026.
We introduce uracil–triazole–pyrene peptidomimetics whose tunable peptide linkers precisely control light emission, copper binding, and interactions with DNA and RNA. Fine structural adjustments unlock selective biomolecular recognition and striking metal‐ and membrane‐responsive fluorescence, paving the way for a new generation of multifunctional ...
