This study developed fluoroalkyl-based polar molecules exhibiting spontaneous orientation polarization in vacuum-deposited films with a surface potential growth rate of over 200 mV/nm relative to the film thickness. Furthermore, the author revealed that introducing dipolar layers between organic/organic interfaces modulates charge injection barriers in OLEDs to improve device performance.
