基于TADF的电致发光，即热激活延迟荧光，在Sn 4 +-卟啉配合物中得到证实。在短电脉冲激发下，可以清楚地观察到即时和延迟的电致发光成分。延迟成分由TADF和磷光组成（见图），TADF成分随温度升高而显著增加。
Electroluminescence based on TADF, that is, thermally activated delayed fluorescence, is demonstrated in Sn4+-porphyrin complexes. On excitation by a short electrical pulse, prompt and delayed electroluminescence components were clearly observed. The delayed component was composed of both TADF and phosphorescence (see figure), and the TADF component significantly increased with increasing temperature.
