Outline of Final Research Achievements

This project aims at the establishment of a widely applicable methodology for precisely assembling organic π-conjugated units, thereby enabling organic electronic materials to exercise their maximum potential. Examined during this grant period was the construction of crystalline frameworks wherein insoluble or unstable large π-conjugated units constitute the main framework. In order to achieve this, the "precursor approach" was employed, by which a soluble precursor compound is quantitatively converted to a target compound via an external stimulus such as heat or light. The research effort led to the successful synthesis of the targeted organic building units that were specifically designed for the above-mentioned crystalline frameworks. Further, it was found that a new compound with a so-far-unreported structural motif could form with one of the new building units. These results will pave the way toward a new class of organic electronic materials.
