Drastic Mechanochromic Luminescence Through Fluorescence–Phosphorescence Switching in a Heavy‐Atom‐Free Organoboron Compound

open access: yesAdvanced Optical Materials, EarlyView.
A new heavy‐atom‐free, donor–acceptor‐type organoboron luminophore has been synthesized, which exhibits red room‐temperature phosphorescence (RTP) in the crystalline state. Furthermore, the amorphous solid generated by grinding shows green thermally activated delayed fluorescence (TADF), displaying distinct mechanochromic luminescence (MCL) through ...

Interior and Exterior Boron Doping in Functional Azacalixarenes Triggering Narrowband Delayed Fluorescence

open access: yesAdvanced Optical Materials, EarlyView.
A unique regioselective interior/exterior borylation strategy is presented for the one‐shot synthesis of two distinct organoboron luminophores from a common macrocyclic azacalix[3]arene. This interior/exterior borylation imparts the material with remarkable TADF properties and narrowband emission capabilities, spanning the violet to blue spectral ...

Effects of Extreme Mirror Downscaling on Open Micro‐Fabry–Perot Spectral Responses and Resonant Mode Profiles

open access: yesAdvanced Photonics Research, EarlyView.
Extreme miniaturization of Fabry–Perot cavities has severe impacts on their spectral response and spatial distribution of the resonant modes. A fully analytical methodology is proposed accounting for the finite borders of the micromirrors to predict this behavior. Model validation relies on comparing with measurements obtained on silicon micro‐cavities
