Circularly polarized luminescence(CPL) is of importance to advance science and technology with significant potential applications in information storage, spintronics and optoelectronic devices. Integrating CPL and the emission mechanism of thermally activated delayed fluorescence(TADF) has attracted considerable attention, because of their 100% internal quantum efficiency in theory and easily modified molecular structures for tunable photo-electrical properties. however, the typical donor-acceptor(D-A) architecture of CP-TADF emitters generally induces a broad emission profile with inferior color purity due to their large structural relaxation under the processes of excitation and emission. Recently, CP-multi-resonance(MR)-TADF emitters that concurrently display CPL activity, narrowband emission and high efficiency are emerging as the most suitable candidates for the next-generation organic light-emitting diode(OLED) display. In this review, the progress of CP-MR-TADF materials is reviewed in terms of the molecular design strategy, the common relationship between the molecular structures and optoelectronic properties, and their OLEDs performance. Finally, the opportunities and challenges in this research topic are discussed.

The Reformatsky reagent derived from ethyl bromoacetate circumvents the challenge associated with the direct regio-and enantioselective iridium-catalyzed allylic alkylation with an unstabilized aliphatic ester enolate. Notably, this work represents the first example of using a Reformatsky reagent in a metal-allyl reaction, which permits the direct construction of enantioenriched β-stereogenic homoallylic esters without preactivation of the pronucleophile or post-reaction modification of the product(e.g., thermal decarboxylation of a 1,3-dicarbonyl). Moreover, the process allows the coupling of a broad range of sterically and electronically diverse electrophiles bearing aryl, heteroaryl and alkenyl derivatives, including the significantly more challenging alkyl-substituted allylic carbonates. The versatility of the ester product is exemplified by a series of functional group manipulations and the development of a concise and efficient enantioselective total synthesis of the natural product,(+)-descurainolide A. Finally, mechanistic studies indicate that the zinc enolate behaves as a soft nucleophile that undergoes outer-sphere alkylation.

Dear Editor,Atovaquone(ATO),a mitochondrial inhibitor,has anti-cancer effects[1].Based on ATO,we developed mitochondria-targeted atovaquone(Mito-ATO)that had even stronger anti-tumor efficacy than ATO[2].we syn-thesized Mito-ATO by attaching the bulky triphenylphos-phonium(TPP)group to ATO via a ten-carbon alkyl chain(Supplementary file of methods;Supplementary Figure S1).
