Acridone alkaloids. X. 13C-Nuclear magnetic resonance spectra of acridone alkaloids.

Chemical and Pharmaceutical Bulletin, 1983
The 13C-nuclear magnetic resonance spectra of twenty-seven acridone alkaloids including angular pyrano [2, 3-c] acridones and linear pyrano [3, 2-b] acridones have been analyzed and assigned. The information should be useful for the structure elucidation of new acridone alkaloids.

Shaping the Afterglow of Indolo[3, 2‐b]Carbazoles via Modulating Intersystem Crossing (ISC/rISC) and Phosphorescence Rates

Aggregate, Volume 7, Issue 4, April 2026.
In a series of indolo[3,2‐b]carbazoles (X‐ICZ‐p1; X = F, Cl, Br), the afterglow properties are shaped by modulating intersystem crossing (ISC/rISC) and phosphorescence rates. F/Cl‐ICZ‐p1 systems show moderate rates, achieving color‐tunable, dual‐mode afterglow in polymethyl methacrylate from persistent thermally activated delayed fluorescence (pTADF ...

Theoretical Design of Acridone-Core Energetic Materials: Assessment of Detonation Properties and Potential as Insensitive, Thermally Stable High-Energy Materials

ChemEngineering
In this study, we investigated the impact of incorporating energetic substituents such as –NO2, –NH2, –Cl, –F, N-methyl-N-nitro (CH3–N–NO2), and picryl on the detonation performance and stability of acridone-based compounds.

Synthesis of organic compounds of arsenic: the preparation of acridone arsonic acids [PDF]

, 1934
I. The P'reuss and Binz reaction, i.e. the conversion of o- nitrotoluene to anthranilic acid by concentrated alkali, has been extended to 3- nitro4- methylphenyla.rsonic with the formation of 3- amino4- carboxyphenylarsonic acid.II.

Anion‐π+ Type AIE‐Active Photosensitizers for Ferroptosis‐Driven Photodynamic Immunotherapy Against Hypoxic Solid Tumors

Aggregate, Volume 7, Issue 1, January 2026.
An anion‐π+ type AIE photosensitizer (TMTPA NPs) with NIR emission was successfully developed through a sulfidation strategy. With its exceptional mitochondrial targeting abilities and efficient Type I ROS generation, TMTPA NPs effectively trigger ferroptosis.
