Perylene Diimide Molecular Glass: Investigations of Charge Transport

Abstract

A new glass-forming organic semiconductor material was synthesized using a known electron transport material, perylene diimide, and attaching it to a molecular glass in order to allow the material to be solution processed. Devices were made using a simple metal-semiconductor-metal structure and electrodes were selected to produce Schottky diodes. Experiments were carried out to characterize this new molecular glass perylene diimide. The new material shows evidence of traps, hysteresis, and other behaviours that are explored in this thesis. The material shows some potential as an electron transport layer with possibilities of memory storage behaviour.
