Force‐Induced Control of Circularly Polarized Luminescence With Rotaxane Architecture

Angewandte Chemie, EarlyView.
Force‐induced reversible on/off switching of circularly polarized luminescence is achieved with a rotaxane‐based supramolecular mechanophore. The mechanophore, featuring a chiral helicene luminophore, is incorporated as a first network cross‐linker into a double‐network organogel.

Fluorene‐Framework Engineering Enables Narrowband Red Multi‐Resonance Emitters for High‐Efficiency With Negligible Roll‐Off Toward BT.2020

Angewandte Chemie, EarlyView.
σ‐Decoupled C9 fluorene‐framework topology control enables narrowband red MR emitters. SF‐BNO and PF‐BNO share the same BNO core, but differ in closed/open fluorene ring closure. SF‐BNO improves steric shielding and stability, while PF‐BNO enhances PLQY, orientation, and efficiency. Ex‐PSF and TE‐OLED architectures deliver ultra‐low efficiency roll‐off
