Abstract
Research into the synthesis of organic semiconductors has revealed many promising traits in their use as a current-carrying compound: durability, high conductivity of electrons, and cheap production. Due to these desirable traits, organic semiconductors can be found in circuitry elements in devices such as solar panels, flexible display monitors, televisions, cell phones, and a wide variety of biological and chemical sensors. Experiments have shown that increasing the size of the compound by adding conjugated cyclic carbons increases the electron mobility of organic semiconductors. This research project aimed to construct a stable, soluble, and highly conductive heterohexacene consisting of six conjugated rings. After seven steps of chemical reactions and purification, a six-membered ring was constructed; NMR spectroscopy and X-ray crystallography have characterized the compound. Electrical conductivity has also been shown through fluorescent radiation when exposed to UV light, and the compound's stability has been tested through exposure to air and a wide range of temperature. Once the compound is successfully oxidized, the TIPS-substituted heterohexacene will join a small group of commercially viable and stable heterohexacenes.
