Abstract

An
organic compound (1'-4-iodophenyl) trihidroxysilane (OH-IPhSi) functionalized
as hole transporting material was synthesized and used as interface
self-assembled monolayers (SAM) on ITO film. To analyze the effect of a SAM
layers on the characteristics an organic light emitting diode (Organic LED), a
typical Organic LED device (ITO/OH-IPhSi/polymer/LiF/Al) was fabricated. The
SAM-treatment ITO device performed a higher mobility than the bare ITO device. The
carrier mobility properties were calculated by space-charge-limited current
measurements (SCLC) technique for polyfluorene (PFO) polymer Organic LED
devices.

Abstract

Hole
taşıma malzemesi olarak işlev gören bir organik bileşik (1'-4-iyodofenil)
trihidroksisilan (OH-IPhSi) sentezlendi ve indiyum kalay oksit (ITO) anodu
üzerinde kendinden organize tek tabaka (KOT) olarak kaplandı. Bir KOT katmanının,
bir organik ışık yayan diyot (Organik LED) üzerindeki etkisini araştırmak için,
tipik bir Organik LED cihazı (ITO / OH-IPhSi / polimer / LiF / Al) yapılmıştır.
KOT ile modifiye edilmiş cihaz, çıplak ITO cihazından daha yüksek bir mobilite göstermiştir.
Bunun yanı sıra, yüklerin mobilite özelliklerinin, polifloren (PFO) polimer Organik
LED cihazları için space charge limitli akım (SCLC) tekniği kullanılarak hesaplanmıştır.
