Sticker-Type Alq(3)-Based OLEDs Based on Printable Ultrathin Substrates in Periodically Anchored and Suspended Configurations

Abstract

Introducing two-dimensional post arrays and a water-soluble sacrificial layer between an ultrathin substrate and a handling substrate provides controllability of the interfacial adhesion in a stable manner. The periodically anchored and suspended configuration after the chemical etching process facilitates the development of, for example, printable Alq(3)-based OLEDs that can be attached to unconventional surfaces.
