Abstract
This study presents a novel design strategy involving sterically demanding 2,4,6-triisopropylphenyl (TPP)-substituted tris(2,4,6-trichlorophenyl)methyl (TTM) radicals and diradicals, achieving bright intrinsic emission in crystalline, powder, and amorphous states without doping or matrix assistance. Single-crystal analysis combined with theoretical calculations reveals that bulky substituents significantly suppress intermolecular interactions, providing valuable insights into the mechanism of radical-based solid-state luminescence (e70100).
