THE PREPARATION OF INSOLUBLE HOLE-TRANSPORT LAYER VIA CATIONIC INDUCED RING-OPENING POLYMERISATION OF OXETANE-DERIVATIZED MATERIALS BY POLY(3,4-ETHYLENEDIOXYTHIOPHENE)
Abstract: The oxetane-derivatized hole
conductors as well
as oxetane-derivatized electroluminescent materials can be
polimerised via cationic ring-opening polymerisation without deterioration of
their electrical and
electro-optical properties. It
is allowed for
the fabrication of
electronic multilayer devices
via solution process. The
polymerization is initiated by oxetane ring opening and results an insoluble
layer. In this work, this
polymerization is called
crosslinking and it
is initiated by
proton which is
supplied by poly(3,4-ethylenedioxythiophene). The insoluble hole transport layer is
successfully fabricated by added NASbF6 and N(C4H9)4SbF6 as
electrolyte salts. Their
applications in hole-only
devices show the
threshold voltage about 75V/µm.
