Shedding a blue light : A series of oxetane‐functionalized crosslinkable triphenylamine dimers (XTPDs) is investigated as the hole‐transport layers in blue‐phosphorescent polymer light‐emitting diodes (see scheme). These devices have improved performance characteristics, and their luminous efficiencies depend on the HOMO energies of the XTPDs.
