Rapid Access to Emission‐Tunable Organelle‐Targeted Aggregation‐Induced Emission Luminogens Through One‐Pot Skeletal Editing

open access: yesTransformative Chemistry, Volume 1, Issue 1, December 2025.
Herein we report a skeletal editing strategy for rapidly transforming readily available isoquinolines into synthetically challenging (dihydrodibenzo[c,i]phenanthridin‐6‐yl)diphenylphosphine oxides (DHBPPO) derivatives. These DHBPPO derivatives exhibit tunable emission, aggregation‐induced emission (AIE) properties, organelle‐targeted specificity, and ...

Mise en évidence d'une résistance aux trypanocides parmi des souches de Trypanosoma congolense récemment isolées au Burkina [PDF]

open access: yes, 1984
Dix-huit souches de T. congolense ont fait l'objet d'une épreuve de sensibilité à l'acétate de diminazène et à l'isométamidium chez la souris. L'intérêt et les limites de cette épreuve sont discutés. Les 13 souches de T.

In Pursuit of Low Energy Phosphorescence: Late Metal Coordination Complexes of the Planar, π‐extended Bipyridyl Ligand 6,6′,7,7′‐Biphenanthridine

open access: yesChemistry – A European Journal, Volume 31, Issue 63, November 12, 2025.
Abstract The coordination chemistry of the planar, doubly π‐extended bipyridine analog, 6,6′,7,7′‐biphenanthridine (p‐biphe), is presented. The phenanthridine units in p‐biphe are fused together at the 6‐ and 7‐ positions, and the resulting rigid ligand is compared with the more flexible parent “biphe” fused only at the 6‐positions.

Palladium–mediated organofluorine chemistry [PDF]

open access: yes, 2014
Producción CientíficaThe substitution of fluorine for hydrogen in a molecule may result in profound changes in its properties and behaviour. Fluorine does not introduce special steric constraints since the F atom has a small size. However, the changes in

Multistep Reactions Initiated by Amine‐Based Organometallic Methods

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 40, October 29, 2025.
The advent of C–H activation and other organometallic methodologies making use of transient directing groups or free amines themselves for the elaboration of amine substrates provides unique access to cascade‐type reactions that can generate significant molecular complexity in one pot. The pursuit of atom‐ and step‐economical pathways to access complex

Trypanosoma brucei aquaglyceroporin 2 is a high-affinity transporter for pentamidine and melaminophenyl arsenic drugs and the main genetic determinant of resistance to these drugs [PDF]

open access: yes, 2017
Objectives Trypanosoma brucei drug transporters include the TbAT1/P2 aminopurine transporter and the high-affinity pentamidine transporter (HAPT1), but the genetic identity of HAPT1 is unknown. We recently reported that loss of T. brucei aquaglyceroporin

Visible Light-assisted Deconstruction/Refunctionalization of Strained and Unstrained N-Cycloalkylanilines [PDF]

open access: yes, 2022
The exploitation of ring strain as a driving force to facilitate chemical reactions is a well-appreciated principle in organic chemistry. Of the strained carbocycles frequently explored in this respect, cyclopropane ring systems have drawn considerably ...

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

open access: yes
Quinolino[4,3-j]phenanthridines were synthesized from para-terphenyl-2,2′′-diamines, which were obtained by cross-coupling reactions. The diamines were converted into amides and ortho-cyclized to quinolino[4,3-j]phenanthridines using Morgan-Walls ...
