Thermally activated delayed fluorescence (TADF) materials are promising for a wide range of applications, including organic light-emitting diodes (OLEDs) and bioimaging. In this study, we introduced electron-withdrawing groups into a CzTRZ framework to achieve both enhanced charge-transfer character and molecular planarity, thereby enabling the coexistence of TADF and two-photon absorption (2PA) properties. This work provides a molecular design strategy for high-performance emissive materials and paves the way for next-generation bioimaging and organic optoelectronic device applications.
