摘要： Currently, the fabrication of high-resolution OLEDs remains great limitations. Electrochemical polymerization is an efficient way to fabricate conducting polymer films. However, the control of the structures and dedoping of films is difficult, thus making the films rough and incapable with flat-panel devices. In this review, the molecular design and the fabrication of high-quality electrochemical polymerization films and super-resolution RGB displays are introduced. Inspired by the unique electrochemical features of N-alkyl carbazoles, highly luminescent precursors are designed with the spatially separated emissive cores and side carbazoles. The films with low doping levels, high luminescent efficiencies and smooth morphology are prepared by optimizing potential windows, electrolyte solutions, scan rates and post-washing process. The luminous efficiency of OLEDs where the films as light-emitting layers exceeds that of most OLEDs prepared by conventional methods. Then electrocopolymerization and multilayer electropolymerization techniques are developed, in which the components and thickness of films can be precisely controlled, endowing the films and OLEDs with superior stability. Finally, RGB active-matrix OLEDs and super-resolution displays of 2822 ppi are achieved. The above works demonstrate electrochemical polymerization is an emerging technique in RGB super-resolution displays and has great commercial potential.
