A series of pyrene derivatives with different asymmetrical substituents were successfully synthesized and characterized.The geometrical electronic structures of the asymmetrical pyrene derivatives were performed by density functional theory(DFT) calculations.The results of photophysical spectra and electrochemical analysis indicated that the optical or electric properties of the pyrene derivatives could be tuned by adjust the π-conjugation lengths of the substituents.Furthermore,through a phase exchange self-assembly method,the highly organized morphologies were observed by SEM.
A series of pyrene derivatives with different asymmetrical substituents were synthesized synthetically and characterized. The geometrical electronic structures of the asymmetrical pyrene derivatives were performed by density functional theory (DFT) calculations. The results of photophysical spectra and electrochemical analysis indicated that the optical or electric properties of the pyrene derivatives could be tuned by adjusting the π-conjugation lengths of the devices. Future and through a phase exchange self-assembly method, the highly organized morphologies were observed by SEM.
