The major goals of the proposed research is to explore self-assembly of organic charge-transfer crystalline materials with emerging properties. Materials-by-design and self-assembly principles are applied to organic functional materials to control their morphology, interface, and crystalline structures. The centimeter-sized charge transfer crystalline superstructures are achieved, which pave the way for the study of their intrinsic multifunctional properties, such as dielectric, magnetic, optoelectronic, and magnetoelectric coupling behaviors. The control of organic crystallization and interfacial electron coupling are keys to dictate external stimuli-responsive behaviors in organic charge-transfer superstructures. The integrated experimental and computational study reveals the importance of chemically driven interfacial coupling in organic charge-transfer superstructures. Such degree of engineering opens up a new route to develop a new generation of functional organic materials, enabling important advance in all-organic electronics. In this project, we aim at utilizing the material design and assembly strategies to rationally develop organic multiferroic-photovoltaics. Instead from trial-and-error design, we combine atomic-scale theoretical prediction and supramolecular assembly engineering to discover new stimuli-controlled multifunctional properties, in addition to the breakthroughs of optoelectronic device performance. The new multifunctional materials with air stability developed by us are critical for ubiquitous optoelectronic and multiferroic applications.
