A Mild and Practical Synthesis of Biphenyl Compounds

open access: yesJournal of Chemical Research, 2012
A mild and practical synthetic route for biphenyls is established. Isopropyl nitrite was prepared from sodium nitrite, isopropanol and hydrochloric acid. The biphenyl compounds were obtained from the diazotisation of aniline derivatives with the generated isopropyl nitrite and the coupling reaction with benzene derivatives in the presence of CuCl as a

Vacuum‐Evaporated, Lead‐Free RbYbI3 Perovskite Interlayers for Universal Electron Injection in High‐Performance Organic Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
ABSTRACT The optoelectronic performance of organic light‐emitting diodes (OLEDs) is critically governed by charge injection from electrodes into organic layers, where significant energy barriers at the interfaces often impede efficient charge injection.

Hybridized Charge‐Transfer Window within a Fully Conjugated Multi‐Resonance Thermally Activated Delayed Fluorescence Framework for Ultrafast Reverse Intersystem Crossing and High‐Efficiency in Deep‐Blue Organic Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
A hybridized charge‐transfer window combining short‐range and long‐range charge transfer is realized within a fully conjugated multi‐resonance thermally activated delayed fluorescence framework. The resulting excited‐state hybridization minimizes the singlet–triplet energy gap (0.04 eV) and enables ultrafast reverse intersystem crossing (krISC = 2.1 ...

Bay‐functionalized [7]Helicene Bilayer Nanographenes

open access: yesAdvanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

An Organometallic [2]Catenane With Pt‒(di‐NHC)‒Pt Units: A Topology‐Driven Strategy for Enhanced Phosphorescence in Discrete Aggregates

open access: yesAngewandte Chemie, EarlyView.
The mechanically interlocked Borromean rings are stabilized by π···π stacking interactions while the [2]catenane is stabilized by solvophobic effects. While the π···π interactions in the Borromean rings lead to severe luminescence quenching, the solvophobically assembled [2]catenane effectively circumvents these interactions, simultaneously restricting
