The effect of the substitution position of dibenzofuran on the photophysical and charge-transport properties of host materials for phosphorescent organic light-emitting diodes
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. Copyright
