Abstract

Interface engineering has an important role on performance of optoelectronic devices. Self-assembled monolayers (SAMs) have been used between indium tin oxide (ITO) and organic layer to obtain high performance from organic light-emitting diodes (OLEDs). Herein, 4-Methoxyphenyl Boronic Acid and 3,5-Dimethoxyphenyl Boronic Acid have been used to ITO as an interface layer. The effect of SAMs on device performance was analyzed electrically and optically. Additionally, surfacre topography of modified ITO was characterized by atomic force microscope and surface wetability was analyzed by contact angle. According to results that has obtain, modified devices show better performance than unmodified devices.

Özet

Ara yüzey iyileştirmeleri optoelektronik cihazların performansı üzerine önemli bir role sahiptir. Kendiliğinden organize olan tek tabaka molekülleri indiyum kalay oksit (ITO) ile organik katman arasında kullanılarak organik ışık yayan diyotlardan (OLEDs) daha yüksek performans elde edilmesi sağlanır. Bu çalışmada ITO’yu modifiye etmek için 4-metoksifenil boronik asit ile 3,5-dimetoksifenil boronik asit molekülleri bir ara yüzey katmanı olarak kullanılmıştır. Kendiliğinden organize olan moleküllerinin cihaz performansı üzerine etkisi elektriksel ve optiksel olarak analiz edilmiştir. Buna ek olarak, modifiye edilmiş ITO’nun yüzey morfolojisi atomik kuvvet mikroskopu (AFM), yüzey ıslanabilirliği ise temas açısı yöntemi ile ölçülmüştür. Elde edilen sonuçlara göre, ITO yüzeyi kendiliğinden organize olan moleküller ile modifiye edilen cihazların modifiye edilmemiş cihazlara göre daha iyi performans sergilediği görülmüştür.
