Recent Progress in Organic TADF Emitters Containing Heavy Atoms

open access: yesAdvanced Optical Materials, EarlyView.
In this review, progress on heavy atom use in organic TADF emitters to produce internal and external heavy atom effects is summarized. Impacts on molecular geometry, TADF efficiency, and performance in OLEDs are discussed. An outlook on the challenges and opportunities of heavy atom incorporation is provided.

Dearomative, Intramolecular Bromoetherification of Carbohydrate‐derived Glycosyl Furans: Access to Enantiopure 6‐Bromo‐Furo[3,2‐b]furans

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract Glycosyl furans represent versatile chiral platform molecules that can be readily accessed via the Garcia Gonzalez reaction. Herein, we report a dearomative, intramolecular bromoetherification of carbohydrate‐derived glycosyl furans to generate enantiopure 6‐bromo‐furo[3,2‐b]furans in up to 69% yield. The method employs N‐Br aromatic amides as

Synthesis of Polysubstituted Naphthalenes via Metal‐Free Borylative Cyclization of o‐Alkynylstyrenes

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A selective, metal‐free method for the synthesis of boron‐functionalized polysubstituted naphthalenes via BCl3‐mediated cyclization of α‐substituted o‐alkynylstyrenes is described. The reaction exhibits broad substrate scope, tolerating various groups such as ethers, sulfides and halogens, and delivers high yields under mild conditions, even ...
