We propose new dual core chromophore materials with blue emission. One of these derivatives, TP‐AP‐TP, exhibits a high luminance EQE value of 7.51% and twice the lifetime of a commercialized material, MADN. The dual core chromophore materials have narrower PL and EL spectra and better thermal properties than the single core chromophore materials.
