However, their application as nonsensitized thermally activated delayed fluorescence (TADF) emitters is hindered by long emission lifetimes. Herein, we describe an approach to improving blue MR\u2010TADF emissions by incorporating a DBANA\u2010derived framework into Pt(II) complexes via cyclometalation. By judiciously combining the framework with an\n                    <jats:italic>N<\/jats:italic>\n                    \u2010heterocyclic carbene to form bidentate chromophoric ligands, the MR\u2010B\/N core still dominates the lowest\u2010lying singlet and triplet excited states of the resulting Pt(II) complexes. The Pt\u2010modified MR emitters exhibit efficient blue emissions with peaks at approximately 460\u00a0nm and a full width at half\u2010maximum of &lt; 30\u00a0nm. The incorporation of the Pt atom shortens the delayed fluorescence lifetime to 5.0\u201311.4 \u00b5s.
