A Modular Approach to Tuning Emissive -Quinolyl Through-Space Charge Transfer States Using sp-Scaffolds.

We have shown that palladium-catalyzed cascade processes provide modular access to rigid quinoline-containing tetracyclic amines. This modular approach enables fine-tuning of the through-space charge transfer (TSCT) state formation between the lone pair localized on the nitrogen atom in the cage moiety and the quinoline moiety by variation of both the intramolecular -aryl distance and quinoline substitution. Decreasing this -aryl distance enhances the formation of the TSCT species, giving control over the emission color and photoluminescence quantum yield.

Suppression of Dexter transfer by covalent encapsulation for efficient matrix-free narrowband deep blue hyperfluorescent OLEDs.

Hyperfluorescence shows great promise for the next generation of commercially feasible blue organic light-emitting diodes, for which eliminating the Dexter transfer to terminal emitter triplet states is key to efficiency and stability. Current devices rely on high-gap matrices to prevent Dexter transfer, which unfortunately leads to overly complex devices from a fabrication standpoint. Here we introduce a molecular design where ultranarrowband blue emitters are covalently encapsulated by insulating alkylene straps.

Long-term overall survival in patients undergoing liver resection for metastatic anal squamous cell carcinoma.

Background And Objectives: There is limited research on management of metastatic anal canal squamous cell carcinoma (SCC) to the liver. This study aimed to describe outcomes for patients undergoing liver resection of anal SCC metastases.

Methods: A multicenter, retrospective cohort study was conducted by three tertiary-referral centers.
