| Popis: | 99 We used amide bond formation and Knoevenagel Reaction to synthesize propeller-shaped triphenylamine-based dendrimers G0, G1 and the others C0, C1 which utilize cyanostilbene as core unit. By using thermal analysis, spectroscopy, microscopy, electrochemical method, we could observe their thermal, photophysical, nanostructure and electrochemical properties. All the aggregation-induced emission (AIE) or aggregation-induced enhance emission (AIEE) character of them, by restriction of intramolecular rotation (RIR) mechanism or through molecular structure packing arrangement in the solid-state. The triphenylamine group can be polymerized by electrochemistry and the polymer film have electrochromic character. The most special thing that we can control the switching behavior of the solid state emission by electrochemistry. The property can be applied in various electronic devices. |
