Importance of the Project
My research focusses on the synthesis of new organic semiconductors with key, tuneable properties for uses in organic electronics such as photovoltaic cells (solar cells), organic light emitting diodes, and field effect transistors. If liquid crystalline, these can be used in liquid crystal displays (LED) for electronics as well.
Existing State of Knowledge
Triazines are an aromatic, electron-poor compound with great electronic and optical properties when donor groups, such as heterocycles, are substitued on them. These trisubstituted triazines provide a nice disc-shaped molecule capable of pi-stacking and thus transporting charge. Once functionalized, these molecules should obtain microphase segregation in order to self-organize better and transport charge even more efficiently due to better overlap and stabilization.
Functionalization of the heterocycles prior to substitution of the triazine is the main focus of the research. These functionalized groups will be thioether groups and branched alkyl chains. These should help induce liquid crystalline structure and contribute to the self-organizaiton of these molecules.
