Low charge transport efficiency limits the switching speed and brightness of organic electronic components. Improving mobility reduces power consumption and increases device responsiveness.

Low intrinsic electrical conductivity in organic molecular layers limits device switching speeds and efficiency. Overcoming this bottleneck enables high-performance thin-film transistors and light-emitting diodes.

Spirobifluorene derivatives are primarily engineered to address the tendency of organic thin films to crystallize or degrade under operational heat. High glass transition temperatures prevent structural deformation that leads to device failure.
