abstract = "A series of thermally activated delayed fluorescence (TADF) emitters of TrzCz1 and TrzCz2 are synthesized to study the effect of linker engineering on the TADF properties. Photophysical and electrical properties of TADF emitters were characterized by the electron donating strength of the molecule by integrating biscarbazole and t-butylcarbazole electron donating units and triazine electron withdrawing unit. Energy bandgap between the highest occupied molecular orbital (HOMO) and the lowest occupied molecular orbital (LUMO) was tuned by changing the electron donating strength of the molecule. t-butylcarbazole based molecule TrzCz2 (0.13 eV) showed smaller singlet-triplet energy gap than TrzCz1 (0.20 eV), and the maximum photoluminescence emission peaks of TrzCz1 and TrzCz2 were 443 and 433nm. TrzCz1 device showed maximum external quantum efficiency of 22.4\% with a CIE color coordinate of (0.17, 0.28) and TrzCz2 showed maximum external quantum efficiency of 9.9\% with a CIE color coordinate of (0.15, 0.09).",
