Two-Photon Excited Near-Infrared Phosphorescence Based on Secondary Supramolecular Confinement. [PDF]
Adv Sci (Weinh), 2022 A multi‐stage assembly strategy involving macrocyclic confinement and nano‐confinement is reported, which induces and enhances guests’ phosphorescence with two‐photon absorption and NIR emission. Moreover, the assemblies possess excitation‐dependent emission properties, in which luminescence covers the visible and NIR regions under different excitation

Achieving White‐Light Emission Using Organic Persistent Room Temperature Phosphorescence
Angewandte Chemie, Volume 135, Issue 32, August 7, 2023., 2023 White‐light emission can be realized by purely organic phosphorescent emitters using either single‐component or host‐guest systems by mixing two fundamental colors (blue and yellow) or three primary colors (blue, green and red). Here we describe current strategies for achieving white phosphorescence at room‐temperature using organic emitters.

Angewandte Chemie, Volume 136, Issue 12, March 18, 2024.Boron‐containing species were threaded through macrocycles bearing a 2,2’‐biphenol unit. The new threaded species exhibited interesting fluorescence features with quantum yields up to 91 % and an enhanced photostability. Their properties were rationalized with quantum chemistry to unravel the vibronic contributions.
