Persistent Room‐Temperature Phosphorescence from Purely Organic Molecules and Multi‐Component Systems

Advanced Optical Materials, Volume 9, Issue 20, October 18, 2021., 2021
Room‐temperature phosphorescence (RTP) materials have received much attention for applications in security printing, sensors, organic light‐emitting diodes, and bioimaging. Considering the slow rate of intersystem crossing processes in organic molecules, it is still challenging to develop new types of RTP materials with high quantum yields and long ...

Threading a Linear Molecule Through a Macrocycle Thanks to Boron: Optical Properties of the Threaded Species and Synthesis of a Rotaxane

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.
