Dissimilar one-dimensional self-assembled structures induced by position of substituents on azobenzene molecules |
| 초록 |
To investigate the morphologies and fluorescent properties of self-assembled aggregates, we synthesized two trigonal compounds with three methoxy groups at the meta (3mMeOAz) and para (3pMeOAz) positions. The two compounds show different color, solubility, morphology, and photoresponsive property. Photoisomerization process of the trigonal compounds were detected by NMR and absorption spectroscopic measurements. Upon UV light irradiation, while the proton signals related to the aromatic rings are shifted to upfield in 3mMeOAz because of its molecular structure change, 3pMeOAz shows excellent photostability. OM, FOM and Scanning electron microscopy (SEM) observations are applied to confirm their morphologies of the self-assembled structures generated from chloroform-methanol, chloroform-hexane and N,N-dimethyl formamide-water mixed solutions. The substituent position effect on the morphologies and photoresponsive properties of the fabricated assembled structures will be discussed. |
