Role of the Recombination Zone in Organic Light‐Emitting Devices
Advanced Materials, EarlyView.This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Functionalized fluorenes via dicationic electrophiles [PDF]
Tetrahedron Letters, 2019 Dicationic fluorenyl cations are shown to react with nitriles to provide amide-functionalized fluorenes. A similar reaction with alcohols gives ether derivatives. The chemistry is initiated by the reactions of N-heterocyclic ketones in a superacidic solution. This leads to cyclizations involving 2-biphenyl groups and formation of the reactive fluorenyl

Advanced Materials, EarlyView.Aggregation‐induced emission strategy is first used to overcome aggregation‐caused quenching in Y‐series acceptors. By integrating tetraphenylethylene, the dTPE exhibits three‐fold PLQY enhancement and significantly suppressed non‐radiative energy loss. An ultra‐low Eloss of 0.130 eV and a record VOC of 0.93 V are achieved, resulting in a PCE over 20.5%

Advanced Materials, EarlyView.Due to excellent physical and chemical stability, the novel designed fluorine‐free polymers with aliphatic‐chain backbones (SP‐PAC12‐QP) are regarded as promising and universal alternatives to perfluorosulfonic acid membranes. Their performances are further improved by physical reinforcement, where the fuel cell performance under high temperature and ...
