The partial crystallization that causes an electrical short circuit to decrease a life of the OLED device is known to be resulted from the π-π stacking between the two-dimensional surfaces of organic semiconducting molecules. The three-dimensional structure is expected to increase the device stability by reducing the π-π stacking tendency. In this study, the syntheses, structural analyses, and optical property assessments of the ethylenediamine-cored π-conjugated compound derivatives are discussed. |
