A twist in the tail : The effect of varying the substitution position of dibenzofuran on its photophysical properties and organic light‐emitting diode device performance was systematically investigated by synthesizing three compounds with 2‐, 3‐ and 4‐substitution patterns (see scheme). The proper selection of substitution position can control the photophysical properties and performance of the materials.
