Covalent Organic Framework‐Based Optoelectronic Memristors: Structural Design, Optoelectronic Modulation and Neuromorphic Applications

Aggregate, Volume 7, Issue 10, October 2026.
This review surveys COF‐based optoelectronic memristors from structural design to neuromorphic applications, tracing how framework‐controlled states become history‐dependent conductance. It also identifies the mechanism validation, reproducible film processing and addressable array integration needed for practical visual hardware.

Tuning the Molecular Rotor Dynamics of Pyrrolo[3,4‐b]Pyridin‐5‐Ones: Steric and Electronic Control of Environmental Sensing

Luminescence, Volume 41, Issue 10, October 2026.
Pyrrolo[3,4‐b]pyridin‐5‐ones are assembled in one pot manner through an Ugi‐Zhu reaction coupled to a cascade sequence (aza Diels‐Alder/N‐acylation/decarboxylation/dehydration). Pyrrolo[3,4‐b]pyridin‐5‐ones are fluorescence probes for local viscosity, polarity, protic environments, and solid‐state emission.

Chlorothiophene‐Substituted N‐Phenylpyrazolines: Synthesis, Anticancer Evaluation, and Computational Insight into COX‐2 Inhibition

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Eight novel N‐phenylpyrazoline derivatives bearing chlorothiophene moieties were synthesized and evaluated for anticancer activity against T47D, MCF7, and WiDr cell lines. Compound 2g showed the strongest cytotoxicity against WiDr cells (IC50 = 19.63 µg/mL) with the highest selectivity index (665.88), highlighting its potential as a selective ...

Imidazo[1,2‐b]Pyrazole‐1,2,4‐oxadiazole Linked 1,2,3‐Triazoles: Synthesis, Antibacterial, Biofilm, and In Silico Studies

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
A collection of innovative imidazo[1,2‐b]pyrazole–1,2,4‐oxadiazole–1,2,3‐triazole hybrids was conceived via the molecular hybridization of bioactive pharmacophores and produced via a CuAAC methodology. The synthesized compounds exhibited strong antibacterial and antibiofilm properties against gram‐positive bacteria.

Green MW/US‐Assisted Construction of Pyrano[2,3‐b]pyridines and Pyrazolo[3,4‐d]pyrimidinones: Pathway Control and Antibacterial Evaluation

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
A rapid, green MW/US‐assisted route was developed for synthesizing coumarin/azacoumarin‐based fused heterocycles. It enables efficient construction of pyrano[2,3‐b]pyridines and pyrazolo[3,4‐d]pyrimidinones under mild conditions. FT‐IR, NMR, MS, and elemental analysis fully confirmed the structures of the new products.
