But stable blue luminescent materials with high electroluminescence (EL) efficiencies and narrow emission spectra are still rare. In this work, two efficient blue molecules (mCPTC and 2mCPTC) are developed by linking large\u2010volume electron donors of 1,3\u2010bis(<jats:italic>N<\/jats:italic>\u2010carbazolyl)benzene (<jats:italic>m<\/jats:italic>CP) and electron acceptor of 2,4\u2010diphenyl\u20101,3,5\u2010triazine (DPTRZ) on the 3,6\u2010di(<jats:italic>tert<\/jats:italic>\u2010butyl)carbazole holder through benzene bridges. Their thermal stability, crystal and electronic structures, energy levels, photophysical property, charge transport ability and EL behaviors are thoroughly studied. They hold high structural rigidity and through\u2010space charge transfer characteristics between donor and acceptor, and exhibit strong deep blue photoluminescence. They can not only function as emitters in OLEDs to radiate deep blue light, but also serve as efficient hosts for blue multi\u2010resonance emitter <jats:italic>v<\/jats:italic>\u2010DABNA, providing narrow EL spectra and excellent EL efficiencies of 24.21\u2009%, much higher than those in common host without sensitizers. These results demonstrate the good potentials of these blue molecules in the fabrication of efficient narrow\u2010spectrum blue
