Organic semiconductors (Os) are crucial in the production of low-cost organic electronic devices like solar cells, OLEDs, and OLETs. Their ability to process at room temperature and tune optical and electrical properties through molecular design makes Os attractive for these applications. However, charge carrier mobility is a significant factor in their performance. The development of stable Os with high charge mobility has significantly advanced the field of organic electronic devices. Discotic Liquid Crystals (DLCs) are a new class of solution processed Os that have shown good charge carrier mobilities of either hole or electron, or both simultaneously. DLCs with structural modifications can demonstrate higher charge carrier mobility in thin films and bulk over a broader temperature range. This proposal aims to investigate the temperature and supramolecular alignment dependence of charge carrier mobilities in proposed DLC compounds. Both temperature and supramolecular studies will be conducted to determine their effect on charge transport over a broad temperature range. The goal is to develop efficient DLCs for use in organic electronics devices, either for standalone use in devices like OFET or as replacement layers in perovskite solar cells. successful implementation of this research will lead to numerous high-impact research papers and patents. The principal investigator believes that this effort will help synthetic chemists and device engineers create high-performing DLCs for organic electronic devices.
