Enhancing Carrier Mobility in Organic Light Emitting Diode Based Polyfluorene by Self-Assembled Monolayers Technique on Indium Tin Oxide

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.

İndiyum Kalay Oksit Üzerinde Kendiliğinden Organize Tek Tabaka Tekniği ile Polifluoren Tabanlı Organik Işık Yayan Diyotun Taşıyıcı Mobilitesinin Geliştirilmesi

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.
