Leveraging Tumor Microenvironment to Boost Synergistic Photodynamic Therapy, Ferroptosis Anti‐Tumor Efficiency Based on a Functional Iridium(III) Complex

Advanced Science, Volume 12, Issue 14, April 10, 2025.
Ingenious introduction of an imine bond into an Ir(III)‐ferrocene complex effectively disrupts the photoinduced electron transfer process. Allowing full use of the TME to boost the efficacy of PDT, the molecule releases the Ir(III) complex and ferrocene with synergistic enhanced therapeutic effects of PDT and ferroptosis.

Label‐Free 3D Cell Imaging Using Hydrogels Functionalized with Switchable Iridium Complexes

Chemistry – A European Journal, Volume 31, Issue 19, April 1, 2025.
A label‐free imaging of cells in a 3D scaffold was achieved using switchable Ir‐complexes, covalently linked to a hydrogel. The presence of unstained cells induces the “switch‐on” of the luminescence from the Ir‐complexes, allowing clear visualization of living cells.

Synthesis of Quinolino[4,3‐j]phenanthridines and their Photophysical Characterization

European Journal of Organic Chemistry, Volume 28, Issue 13, April 1, 2025.
Nine novel quinolino[4,3‐j]phenanthridines were successfully synthesized. UV/Vis and fluorescence spectroscopy revealed remarkable optoelectronic properties. Large Stokes shifts were especially observed for the protonated substrates. The experimental results were compared and complemented with quantum chemical calculations, providing further insights ...

An investigation of a palladium catalysed biaryl synthesis of pyrrolophenanthridine derivatives. Extension of the Heck reaction

Journal of the Brazilian Chemical Society, 2000
N-Benzylisatin derivatives have been found to readily undergo cyclisation via hydrogen halide elimination in a biaryl synthesis reaction when using palladium catalysts, in the absence of phosphine ligands, to yield oxopyrrolo[3,2,1-de]phenanthridine ...

Synthetic Strategies for 5- and 6-Membered Ring Azaheterocycles Facilitated by Iminyl Radicals

Molecules, 2016
The totality of chemical space is so immense that only a small fraction can ever be explored. Computational searching has indicated that bioactivity is associated with a comparatively small number of ring-containing structures. Pyrrole, indole, pyridine,
