However, their development remains hindered by slow reverse intersystem crossing (RISC) rates, which cause severe efficiency roll\u2010off at high luminance and limit their application in high\u2010performance OLEDs. Here, we propose an effective approach for designing blue MR\u2010TADF molecules by integrating a crumpled and asymmetric heptagonal dibenzodiazepine building block, rather than conventional planar donors, which not only promotes efficient triplet\u2010to\u2010singlet RISC processes but also preserves narrowband emission. The proof\u2010of\u2010concept emitter AzBN2 exhibits a bright deep\u2010blue emission centered at 462\u00a0nm with a full\u2010width at half\u2010maximum of 19\u00a0nm and CIE coordinates of (0.13, 0.067), accompanied by a more than twofold increase in the RISC rate. As a result, TADF OLEDs based on AzBN2 achieved a record maximum external quantum efficiency (EQE) of up to 35.7%. Moreover, ascribed to the improved RISC rates of AzBN2, the device exhibits an extremely low efficiency roll\u2010off; notably,\u00a0the EQE remains at 29.8% under a high luminance of
