Spiroaromatics, a kind of spiro-structure functionalized organic semiconductors, are attracted great and wide focus on improving the photophysical, thermal and morphological stability, optophysical quantum efficiency in solution and/or solid states, especially, and further promoting device efficiency and prolonging operation lifetime for applicable optoelectronic devices. . This project choose novel azaflourene-based spiroaromatic structures to construct novel and abundant azaspiroaromatic derivatives. To obtain the relationship between structures and optoelectronic properties, kinds of filming process methods would be carried out to prepare various thin films with different surfacial morphologies. Equipments such as SEM、TEM、XRD、AFM, etc will be aplied to systematically ellustrate the relationship between crystal structures, molecular structures and properties in devices, especially charge mobility, photoluminescence, electroluminescence and photovoltaic properties. By the systematically construction of lamellar devices, performance optimization, and lifetime test, high stable RGB color and white light emitters, electron transport materials, and special materials will be selected as the commercial available candidates providing a solution for the sustainable chemistry.
