Stepwise Stiffening Chromophore Strategy Realizes a Series of Ultralong Blue Room-Temperature Phosphorescent Materials.

The variable‐temperature phosphorescence spectra of 2CzB@BA were measured, and the emission peaks all showed a decreasing trend as the temperature increased from 77 K to 298 K, proving the absence of a thermally activated delayed fluorescence (TADF) component (Figure 3b ).
