Ms. Bayerl et al., Crosslinkable hole-transport materials for preparation of multilayer organic light emitting devices by spin-coating, MACRO RAPID, 20(4), 1999, pp. 224-228
Our approach to prepare multilayer light emitting devices (LEDs) by low-cos
t spin-coating techniques is the combination of spin-coating and photo-cros
slinking. The oxetane functionality was used as the polymerizable moiety, w
hich was crosslinked in bulk by a cationic mechanism. The resulting films w
ere resistant against solvents used in subsequent spin-coating steps. The s
ynthesis of bis-functionalized hole transporting triarylamines by palladium
catalyzed C-N-coupling reaction, their polymerization, characterization, a
nd first application in two-layer blue light emitting OLEDs are presented.
