Two-dimensional π-conjugated compounds have attracted much attention as organic semiconductors in many applications including OLED, OPV and OFET. However, their poor processibility due to the low solubility in most organic solvents has limitied their application, and their crystallization tendency due to easy π-π stacking of planar structures have decreased a life of the organic semiconducting devices. In this study, we synthesized various<i> N,N,N′,N′</i>-tetrakis(aryl- or stilbenyl)ethylenediamine, starbust-like π-conjugated compounds including an ethylenediamine core unit. Their structures are determined by NMR and IR analyses, and the physical, electrical and optical properties are characterized to show their processibility and thermal stability.
